> This is a prereq for (Rolling Upgrade - Finalize needs to complete upgrade
> states in DB, which can do other work in parallel), and is related to
> (Rolling Upgrade Bootstrap - Allow Ambari upgrade from 1.7.0 - 2.0.0 to
> populate new tables, which prepares the pre-reqs for a downgrade).
> Basically, when a service starts, the response's structuredOut needs to
> contain something like,
> {"version": "2.2.1.0-2175"}
> This Jira captures the python work to be done for all of the services.
> The backend will then store this in the hostcomponentstate table when the
> HeartBeatHandler detects it, and use it to bubble up information into the
> host_version and cluster_version tables
