Bug Description

Keystone is the central identity management system for Openstack as of the Precise / Openstack Essex cycle. It is required for use of dashboard.

I took a crack at charming in python. I like it quite a bit and am wondering if some of the functions in util.py would be good additions to the current charm helper library?

In any case, the keystone charm is working nicely with the supported openstack components. A service must inform keystone of the region, its service type, and its 3 API endpoints (admin, internal, public) and keystone will return to it a unique token, and its auth and service endpoints.

Doing the review in a couple of steps for the sake of time right now:
1. static review
2. promulgate
3. dynamic review in the context of a full openstack deployment

Static review:

- readme: Please add a readme file... the charm browser displays them automatically now. Do whatever makes sense for readme files in the overall context of the set of openstack charms.

- upgrade: What's the upgrade path look like for this charm? There're lots of moving pieces in openstack as a whole... is it even possible? If so, please add an `upgrade-charm` hook/link... if not, please note this in readme.

discussion/recommendations:

- [eventually] definitely split utils.py out into some charm-helpers-python tools

- [eventually] maybe extract your 'valid_service' stuff out into charm-helpers too... that'd be generally useful

- [wishlist] I like your config_get wrapper... I'd love to eventually see one that also allowed for locally persistent config like facter... all hidden behind one config interface. Maybe it's easier to just extend juju to handle `config-set` from a hook... dunno

- stylistically, it's easier to look at only hooks in hooks/... everything else included/linked from something like $CHARM_DIR/lib... no biggie obviously

- really like the debug/verbose options... this is a note to self to recommend that as a best-practice for large/complex/fragile services across the board

---

Please go ahead and promulgate... looks good!

I'll get your help to do tests in a full-stack context next week... filing bugs against the promulgated charm with any problems.
