Add management roles/playbooks

[ansiblejunky]

Managing multiple AAP instances (dev,test,prod) or in different network zones is a challenge. The tasks often performed are:

• start, stop, and restart of services
• healthchecks
• etc

Basic "Day 2" operations on AAP platform.

So, for example, I want to bring AAP down for some maintenance or whatnot, perhaps I run a playbook that ensures all running jobs are stopped, no new jobs are running, and then I shutdown the web layer (controller), the app layer (exec nodes) and then database layer (postgres) in that order to ensure a clean shutdown sequence. A playbook like that would be cool, which uses roles that support managing the different services (postgres, etc)

Or maybe I just want to bounce the postgres database service. Use a playbook/role for that. "aap_manage_postgres.yml" playbook would be called with extra var mode=restart for example.

thanks for the idea, PRs are welcome :) but I do agree that some of those tasks would be useful to have a role to do.
