Remove deprecated auth_token middleware

The actual code for auth_token has been moved python-keystoneclient
since Grizzly, and keep it in keystone for backward compatibility
over Havana Release. So now we can safely remove it in Icehouse.

Style improvements to logging format strings

Added the following improvements:

* Use the logging API to handle formatting of message args, which
  potentially prevents us from having to do a bunch of redundant string
  formatting for logging statements which occur below the runtime's
  logging level. For example, in many places `LOG.debug('foo %s' % bar)`
  has been replaced with `LOG.debug('foo %s', bar)`.
* Similarly, this change also removes a few redundant repr() and str()
  calls. For example: `LOG.error('foo %r', repr(bar))` ->
  `LOG.error('foo %r', bar)`, and the same for %s/str().
* One logging statement included some unnecessary escaping in the log
  message string (e.g., 'foo is a \'bar\'', which was replaced with
  "foo is a 'bar'").
* Added some missing message translation calls.

PasteConfigNotFound also raised when keystone.conf not found

Although keystone is looking for paste configuration on startup, this
exception can also be raised when keystone attempts to look in the
regular keystone.conf file for paste configuration, and can't find that
file either. The solution here is just to make the exception slightly
more generic (ConfigFileNotFound), along with it's rendered error
message and improve surrounding comments to better explain the scenario.
