> 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
