Somehow deleteDatastore was never implemented, that meant:
templates haven't been cleaned up on datastore delete and
also agents have never been informed about storage pool removal.
If a -rst resource wasn't deleted because of a failed copy,
a reoccurring snapshot attempt couldn't be done, because there
was still the "old" -rst resource. To prevent this always
try to remove the -rst resource before, if it doesn't exist it is a noop.

This PR introduces the concept of multi-scope configuration settings. In addition to the Global level, currently all configurations can be set at a single scope level.
It will be useful if a configuration can be set at multiple scopes. For example, a configuration set at the domain level
will apply for all accounts, but it can be set for an account as well. In which case the account level setting will override the domain level setting.
This is done by changing the column `scope` of table `configuration` from string (single scope) to bitmask (multiple scopes).
```
public enum Scope {
Global(null, 1),
Zone(Global, 1 << 1),
Cluster(Zone, 1 << 2),
StoragePool(Cluster, 1 << 3),
ManagementServer(Global, 1 << 4),
ImageStore(Zone, 1 << 5),
Domain(Global, 1 << 6),
Account(Domain, 1 << 7);
```
Each scope is also assigned a parent scope. When a configuration for a given scope is not defined but is available for multiple scope types, the value will be retrieved from the parent scope. If there is no parent scope or if the configuration is defined for a single scope only, the value will fall back to the global level.
Hierarchy for different scopes is defined as below :
- Global
- Zone
- Cluster
- Storage Pool
- Image Store
- Management Server
- Domain
- Account
This PR also updates the scope of the following configurations (Storage Pool scope is added in addition to the existing Zone scope):
- pool.storage.allocated.capacity.disablethreshold
- pool.storage.allocated.resize.capacity.disablethreshold
- pool.storage.capacity.disablethreshold

This PR fixes https://github.com/apache/cloudstack/issues/8638
== Description
Four new Resource Types have been added. Admin can configure corresponding resource limits for the tenants at different levels (domain, account, project)
User dashboard's Storage section will show the new resources, their limits and current usage.
1. backup - No. of backups used by the account
2. backup_storage - Backup storage allocated for the account
3. bucket - No. of buckets used by the accounts
4. object_storage - Object storage allocated for the account.
Some other related changes done to BnR framework:
1. Maximum number of Backups to retain can be specified while creating Backup schedules, similar to Scheduled snapshots.
2. Oldest Scheduled backup of the same interval type will be deleted once the number reaches the configured max Backups value.
3. Code refactor: Moved syncBackups method from BackupProvider to the framework BackupManagerImpl, as it is a common functionality and all providers were using duplicated code.
Changes done to the Object Storage Framework
1. Quota parameter is made mandatory while creating a bucket. Bucket quota is considered to be the allocated space and will be used to enforce Resource limits.
== Schema Changes:
1. New Column `max_backups` added to `backup_schedule` table
4. New Column `backup_interval_type` added to `backups` table
== Api Changes:
1. createBackup: new Parameter `scheduleid`. It should be specified whenever a scheduled backup is created. This will translate to the `backup_interval_type` in the `backups` table.
3. createBackupScheduke: new Parameter `max_backups`. To specify maximum number of backups to retain for the given schedule.
== Configurations:
|Setting |Scope |Default Value |Description|
|-------|--------|--------------|-----------|
|backup.max.hourly |Global |8 |Maximum recurring hourly backups to be retained for an instance|
|backup.max.daily |Global |8 |Maximum recurring daily backups to be retained for an instance|
|backup.max.weekly |Global |8 |Maximum recurring weekly backups to be retained for an instance|
|backup.max.monthly |Global |8 |Maximum recurring monthly backups to be retained for an instance|
|max.account.backups| Global| 20 | The default maximum number of backups that can be created for an account|
|max.account.backup.storage| Global| 400 | The default maximum backup storage space (in GiB) that can be used for an account|
|max.domain.backups| Global| 40 | The default maximum number of backups that can be created for an domain|
|max.domain.backup.storage| Global| 800 | The default maximum backup storage space (in GiB) that can be used for an domain|
|max.project.backups| Global| 20 | The default maximum number of backups that can be created for an project|
|max.project.backup.storage| Global| 400 | The default maximum backup storage space (in GiB) that can be used for an project|
|Setting |Scope |Default Value |Description|
|-------|--------|--------------|-----------|
|max.account.buckets| Global| 20 | The default maximum number of buckets that can be created for an account|
|max.account.object.storage| Global| 400 | The default maximum object storage space (in GiB) that can be used for an account|
|max.domain.buckets| Global| 40 | The default maximum number of buckets that can be created for an domain|
|max.domain.object.storage| Global| 800 | The default maximum object storage space (in GiB) that can be used for an domain|
|max.project.buckets| Global| 20 | The default maximum number of buckets that can be created for an project|
|max.project.object.storage| Global| 400 | The default maximum object storage space (in GiB) that can be used for an project|

* api,agent,server,engine-schema: scalability improvements
Following changes and improvements have been added:
- Improvements in handling of PingRoutingCommand
1. Added global config - `vm.sync.power.state.transitioning`, default value: true, to control syncing of power states for transitioning VMs. This can be set to false to prevent computation of transitioning state VMs.
2. Improved VirtualMachinePowerStateSync to allow power state sync for host VMs in a batch
3. Optimized scanning stalled VMs
- Added option to set worker threads for capacity calculation using config - `capacity.calculate.workers`
- Added caching framework based on Caffeine in-memory caching library, https://github.com/ben-manes/caffeine
- Added caching for account/use role API access with expiration after write can be configured using config - `dynamic.apichecker.cache.period`. If set to zero then there will be no caching. Default is 0.
- Added caching for account/use role API access with expiration after write set to 60 seconds.
- Added caching for some recurring DB retrievals
1. CapacityManager - listing service offerings - beneficial in host capacity calculation
2. LibvirtServerDiscoverer existing host for the cluster - beneficial for host joins
3. DownloadListener - hypervisors for zone - beneficial for host joins
5. VirtualMachineManagerImpl - VMs in progress- beneficial for processing stalled VMs during PingRoutingCommands
- Optimized MS list retrieval for agent connect
- Optimize finding ready systemvm template for zone
- Database retrieval optimisations - fix and refactor for cases where only IDs or counts are used mainly for hosts and other infra entities. Also similar cases for VMs and other entities related to host concerning background tasks
- Changes in agent-agentmanager connection with NIO client-server classes
1. Optimized the use of the executor service
2. Refactore Agent class to better handle connections.
3. Do SSL handshakes within worker threads
5. Added global configs to control the behaviour depending on the infra. SSL handshake could be a bottleneck during agent connections. Configs - `agent.ssl.handshake.min.workers` and `agent.ssl.handshake.max.workers` can be used to control number of new connections management server handles at a time. `agent.ssl.handshake.timeout` can be used to set number of seconds after which SSL handshake times out at MS end.
6. On agent side backoff and sslhandshake timeout can be controlled by agent properties. `backoff.seconds` and `ssl.handshake.timeout` properties can be used.
- Improvements in StatsCollection - minimize DB retrievals.
- Improvements in DeploymentPlanner allow for the retrieval of only desired host fields and fewer retrievals.
- Improvements in hosts connection for a storage pool. Added config - `storage.pool.host.connect.workers` to control the number of worker threads that can be used to connect hosts to a storage pool. Worker thread approach is followed currently only for NFS and ScaleIO pools.
- Minor improvements in resource limit calculations wrt DB retrievals
