Command line client fails without endpoint

[Thomas Herve]

Since 5ed2e70f9f38e46c5af36d1e9c4eb4e24568bc5a, most shell calls fail like this:

$ barbican secret list
Invalid URL u'/v1/secrets': No schema supplied. Perhaps you meant http:///v1/secrets?

_base_url is not used everywhere. endpoint defaults to the empty value, which may be one of the issues.

    Use keystoneclient to get endpoint if it's empty

    We used to rely on keystoneclient code to get the proper endpoint from
    keystone if it was not provided in the command line or as an
    environment variable. This changed in a recent commit. So now that we
    are using an adapter for the keystone sessions, we use the function
    provided by that adapter.
