For HA work items that are created for host state change, checks must be
done when execution is called in a new management server session.
A new column, reason, has been added in cloud.op_ha_work table to track
the reason for HA work.
When HighAvailabilityManager starts it finds and puts all pending HA
work items in Investigating state. During execution of the HA work if it
is found in investigating state, checks are done to verify if the work
is still valid. If the jobs is found to be invalid it is cancelled.

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.

- Adds new config 'vm.ha.enabled' with Zone scope, to enable/disable VM High Availability manager. This is enable by default (for backward compatibilty).
When enabled, the VM HA WorkItems (for VM Stop, Restart, Migration, Destroy) can be created and the scheduled items are executed.
When disabled, new VM HA WorkItems are not allowed and the scheduled items are retried until max retries configured at 'vm.ha.migration.max.retries' (executed in case HA is re-enabled during retry attempts), and then purged after 'time.between.failures' by the cleanup thread that runs regularly at 'time.between.cleanup'.
- Adds new config 'vm.ha.alerts.enabled' with Zone scope, to enable/disable alerts for the VM HA operations. This is enabled by default.
