    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.
