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

> When the host goes down. Cloudstack will try to migrate the VM's for which HA
> is enabled to other hosts in cluster.
> If the migration fails using default Planners due to cluster threshold
> reached, CloudStack HAManager uses an HAPlanner which overrides any threshold
> checks set to avoid such failures.
> This is not seen happening with 4.5 codebase.
