Convert revocation list file last modified to UTC

On a restart of a service using auth_token middleware, the last modified
time of the revocation list file is checked to decide whether to get the
fresh list from keystone. In server timezones that are ahead of UTC,
this compares a local time with UTC. This means whenever a service is
restarted it doesn't update the revocation list for the length of the
timezone offset from UTC.

This change converts the last modified time to UTC when it's first
read, so the comparison is valid.

Reorganize Service Catalog

Currently each service catalog call handles it's own parsing and
filtering. Modify this so that each function calls back to another
public function ensuring that filtering and parsing is only handled
once.

This allows us to consolidate some helper methods into the base class
and generally clean up.

Extract a base Session object

A wrapper around a number of connection variables. This will be extended
later with principals such as Kerberos authentication and http sessions.

The intent is that this session object will become the basis for all
other client library communications in OpenStack (as keystone wants to
control things like authentication for everybody).
