Document host removal

[Adrien Cunin]

The documentation should explain the process to follow in order to remove a host (compute host at first, but others as well) from a running OSA deployment.

[Jesse Pretorius (jesse-pretorius)]

We should probably include the process for decommissioning each grouping of hosts - compute, storage, controllers, swift, etc. They're all sufficiently different and need specialised actions. Bonus points for adding convenience playbooks to the openstack-ansible-ops repository!

[Miguel Alejandro Cantu (miguel-cantu)]

How do you guys feel about the "convenience playbook" utilizing the openstack-ansible inventory?
