This depends on how "safely" you want this...

Just stopping the services and removing the packages should be enough.

I didn't verify what happens if you e.g. later try to run 'engine-cleanup'
(How will it react when trying to remove them?) or re-install (will they
behave as if already setup?) etc.

You can/might then also remove the databases from postgres, e.g.

# su - postgres
psql
drop database ovirt_engine_history;
drop database ovirt_engine_reports;

Not for this per-se, but [1] shows how to migrate them to another machine.

We also have open bugs [2][3] to do this more cleanly, but they'll require
some more work, and it currently does not seem they'll make it to 3.6.
