The new apiclient.exceptions hierarchy is more comprehensive
and it covers almost all HTTP error status codes. These
exceptions can be used in novaclient, keystoneclient,
glanceclient, and other client projects thus providing a
single inteface.
Users can have benefit from OpenStack clients raising exceptions
of known classes while now every client has its own classes making
difficult to catch, e.g., NotFound for every client.

Create a function out of the standard request call that handles common
headers like user agent and logging.
This makes future changes easier to digest.

The Conflict Exception is added for HTTP error code 409.
However this exception is never raised as this class is not added to
the error_code map and always raises the ClientException whenever a
409 code is returned.

Cleans up the code around exception handling and logging
when first authenticating (which often returns an unscoped token).
There's no need to be logging an exception on an expected empty
catalog and moreover the except block was a bare "except" which
could mask other errors.
