> Server side definition of the task and its results
> * Version number as a parameter
> * Manage transition to/from UPGRADING/UPGRADE_FAILED
> Upgrade is performed when a service and all its host-component are in INSTALLED state.
Upgrade preparation step will put all relevant components in UPGRADING state and after upgrade
is successful the task completion will put them back to INSTALLED state.
> If there are any errors then the host-components go into UPGRADE_FAILED state.
> The above states will be used by the FE to infer upgrade status.
> Update current stack version based on Agent task report
