OpenStack Charm work for Saucy/Havana

Registered by James Page on 2013-05-03

[GOAL]
General improvements to OpenStack Charms; specifically:

1) Rationalize charms to all be python based
2) Unit testing
3) Consolidate openstack-charm-helpers (see also charmsupport from Canonical IS)
4) Automated testing of proposed changes (including regression testing back to essex)

[RATIONALE]
The current shell based charms are becoming hard to support; we have todo all work twice for reusable bits (sh and python).
Work is being duplicated across several groups of charmers.

User stories:

John is maintaining some openstack juju charms. When he wants to push a change affecting multiple charms, he does not want to duplicate his work across bash and shell.

Mike wants to ensure deploying specific configuration of OpenStack is supported and tested.

Bob from Bob's Super Storage Systems Inc wants to easily deploy his cinder plugin alongside our Juju charms without making changes to the cinder charm itself.

Risks:

Charm changes break backward comparability with existing upstream charms.
Network configuration being added to charms may conflict with future work in MAAS/Juju wrt network abstraction.

Test Plan:

Implement some automated integration testing on all charm changes, as specified in WIs.

Release Notes:
