This client includes the API version in the URL directly where the
former practice was to include it in the service catalog endpoint.
This change removes the version from the last component of the
SC endpoint (if present) for transition purposes.
Note that this does not generalize to the other APIs
where the version is not the last component of the SC endpoint.
Change-Id: Ie04c38d80b17a171482e195aa1c633b6b6974042
Copied mostly from python-keystoneclient with
some Glance-specific stuff. README.rst shows what
WILL be the way to do things, not what is currently coded :)
