* 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

* Support for Management Server Maintenance
- New APIs: prepareForMaintenance and cancelMaintenance, with required parameter - managementserverid.
- New management server states for maintenance: PreparingForMaintenance, Maintenance.
- listHosts API with optional parameter – managementserverid, to list the hosts connected to the management server.
- Support management server maintenance when more than one active management servers available.
- Triggers transfer agents to other available management servers for maintenance, new agent command MigrateAgentConnectionCommand to initiate transfer of indirect agents.
- New global config 'management.server.maintenance.timeout', to set the timeout (in mins) for the management server maintenance window, default: 60 mins.
- UI changes: Prepare and Cancel Maintenance in Management Server section, Connected Agents tab, New fields for hosts and management servers.
* Updated pending jobs check timer task with ScheduledExecutorService
* keep maintenance state on trigger shutdown call when ms is in maintenance
* add pending jobs count to ms response
* during ms heartbeat, update state to up only when it's down
* allow vm work jobs of async job created before prepare for maintenance
* Revert "keep maintenance state on trigger shutdown call when ms is in maintenance"
This reverts commit 607e13364679eac897f4d146bb3325ea7a61ba17.
* skip maintenance test when multiple management servers are not available, and not configured in host setting for kvm
* Delete local storage properties in agent.properties during delete pool
* Fix stale entry when add local storage failed
* Smaller methods
* Comment added
* 4.20:

Restrict the migration of volumes attached to VMs in Starting state (#9725)
server, plugin: enhance storage stats for IOPS (#10034)
Introducing granular command timeouts global setting (#9659)
Improve logging to include more identifiable information (#9873)
Adds framework layer change to allow retrieving and storing IOPS stats for storage pools. Custom `PrimaryStoreDriver` can implement method - `getStorageIopsStats` for returning IOPS stats. Existing method `getUsedIops` can also be overridden by such plugins when only used IOPS is returned.
For testing purpose, implementation has been added for simulator hypervisor plugin to return capacity and used IOPS for a pool.
For local storage pool, implementation has been added using iostat to return currently used IOPS.
StoragePoolResponse class has been updated to return IOPS values which allows showing IOPS values in UI for different storage pool related views and APIs.
