* 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

Multiple fixes:
1. changes to the mvn configuration
a. include simulator to client.war
b. activate simulator by profile
2. templates for simulator
3. developer prefill for simulator
a. Use deplydb-simulator to setup simulator db
4. Inherit components-simulator.xml from components.xml
5. ListVolumesCommand missed for MockStorageManager
6. Include simulator properties into utils/db.properties
TODO:
Secondary storage VMs don't come up because ComponentLocator doesn't
retain a unique set of adapaters by name. Fix this in subsequent
checkin.
BootArgs carry router priority for master and backup and simulator will
reuse the priority to decide RvR status. Deprecating the odd/even logic.

* SSVM to act as a direct connect agent
* Storage Resources handle SSVM commands
* create-schema.sql already has simulator_network_label. removing the label from create-schema-simulator.sql
