CLOUDSTACK-8079: If the cluster capacity threshold is reached, HA-enabled VM is not migrated on another host during HA

Changes:
-  When there is HA we try to redeploy the affected vm using regular planners and if that fails we retry using the special planner for HA (which skips checking disable threshold)
Now because of job framework the InsufficientCapacittyException gets masked and the special planners are not called. Job framework needs to be fixed to rethrow the correct exception.
- Also the VM Work Job framework is  not setting the DeploymentPlanner to the VmWorkJob.  So the HA Planner being passed by HAMgr was not getting used.
- Now the job framework sets the planner passed in by any caller of the VM Start operation, to the job
