Cleanup no longer used upgrade files

[Marios Andreou]

We should remove many of the files in extraconfig/tasks/ that relate to the Upgrades workflow. In particular for Ocata [1] as the workflow has changed significantly many of the existing files can be removed. Filing a bug for tracking.

Note we have already landed this to master @ https://review.openstack.org/#/c/445816/ Cleanup no longer used upgrade files Change-Id: I7831d20eae6ab9668a919b451301fe669e2b1346
