Revert "Revert "Blacklist support for ExtraConfig""

There is a Heat patch posted (via Depends-On) that resolves the issue
that caused this to be reverted. This reverts the revert and we need to
make sure all the upgrades jobs pass before we merge this patch.

This reverts commit 69936229f4def703cd44ab164d8d1989c9fa37cb.
Closes-Bug: #1699463
implements blueprint disable-deployments
