Code Issues Proposed changes

Allow image and flavor by name for create_server

Browse Source 
We do a bunch of work everywhere else in shade to be friendly - but for
some reason we only accept object or id for image and flavor. Fix it.

In the unit tests, pass in a dict with an id value to avoid the need to
mock the glance client, since that's not really what we're testing in
any of those tests ... but add a test that does not do that to verify
that the glance and nova clients are used to look at image/flavor lists.

features:
- The image and flavor parameters for create_server
now accept name in addition to id and dict. If given
as a name or id, shade will do a get_image or a
get_flavor to find the matching image or flavor.
If you have an id already and are not using any caching
and the extra lookup is annoying, passing the id in
as "dict(id='my-id')" will avoid the lookup.
