This change updates the Key Manager service for the resource2/proxy2
refactoring. Along with making it work with the new classes, it improves
usability--at least temporarily--by exposing the ID value necessary from
the HREFs that the service returns. The HREF that gets returned, e.g.,
from a list call, is not directly usable to then pass it into a get
call. A more long-term fix for this would potentially be to create a Key
Manager specific base class that fiddles around with IDs and looks to
see if they are an HREF and converts them to a UUID in the proper
direction depending on where the data is going, but that's too much to
tackle in this refactoring change.
Besides updating some of the resources to match the documented
attributes, one feature this does add is retrieval of the Secret
payload, which is done via a separate endpoint. However, like other
calls in Glance and Heat, we unify them in the proxy's `get_secret` call
so the user doesn't need to know it's a separate call.
This also includes some basic docs in the user guide to show how the
different ID usage is currently necessary.
