clean up cinder on an unstack

cinder currently has issues that leave volumes around
after tempest tests. Make sure that cinder gets cleaned
up to a zero state on an unstack.sh so that we can reset
the environment.

Handle the new behaviour for invalid instances.

The behaviour of this case changed with bug/836978. Requesting the
status of an invalid instance will now return an error message
including the instance id, so we need to filter that out.

Resolves the devstack elements of bug 836978.

Revert "Create tools/install_prereqs.sh"

This reverts commit 7be0b04

This work breaks the ability to do multi database installs,
revert until there is a working solution here, as this is going
to make fixing postgresql in tempest impossible.
