The find_resource method had two hacks in in to support cinder
and keystone and I have removed those in favor of a monkey patch
for cinder.

The find_resource method used to attempt to UUID parse the id, but
it would do a manager.get anyway.  I changed it to skip the UUID
parsing.  This will make things run minorly faster and it supports
LDAP for keystone.

The find_resource used to attempt to use display_name=name_or_id
when finding.  This was a hack for cinder support, but it breaks
keystone because keystone totally messes up with the bogus filter
and keystone refuses to fix it.

The following logging levels are set according to the combination of
--verbose, --quiet and --debug options:

verbose_level   logging level       options
0               --quiet             ERROR
1               (none)              WARNING
2               --verbose           INFO
3+              --verbose --verbose DEBUG
                or --debug

Logging levels for the requests and iso8601 modules are forced to ERROR.

This is the first step in bp use-logging-not-print

The difference between '--debug' and '--verbose --verbose' is --debug triggers
cliff's exception handling and traceback display.

 - Add support in the common section for extension list. This only
   supports Identity for now. Once the APIs for volume and compute
   are supported in the respective APIs, they will be added. Once
   network is added to this client, it will be added (the API already
   supports it).
 - Include extension fakes for volume and compute for pre-enablement.

There are files containing string format arguments inside
logging messages. Using logging function parameters should
be preferred.

Thinking ahead, a few other upcoming keystone features could
benefit from reading contents from a file. Thus, moving the
function from policy to utils.

Most of the CLIs use a NoUniqueMatch, so produce a useful
error message if that happens.  Added some tests for
find_resource as well.
