Replace namespace/io-stats/io-threads with 3.6-fb versions

This rolls up multiple patches related to namespace identificaton and
throttling/QoS.  This primarily includes the following, all by Michael
Goulet <mgoulet@fb.com>.

  io-threads: Add weighted round robin queueing by namespace
  https://phabricator.facebook.com/D5615269

  io-threads: Add per-namespaces queue sizes to IO_THREADS_QUEUE_SIZE_KEY
  https://phabricator.facebook.com/D5683162

  io-threads: Implement better slot allocation algorithm
  https://phabricator.facebook.com/D5683186

  io-threads: Only enable weighted queueing on bricks
  https://phabricator.facebook.com/D5700062

  io-threads: Update queue sizes on drain
  https://phabricator.facebook.com/D5704832

  Fix parsing (-1) as default NS weight

Parts of the following patches have also been applied to satisfy
dependencies.

  io-throttling: Calculate moving averages and throttle offending hosts

  Shreyas Siravara <sshreyas@fb.com>

  it is enabled

  Alex Lorca <alexlorca@fb.com>

There are also some "standard" changes: dealing with code that moved,
reindenting to comply with Gluster coding standards, gf_uuid_xxx, etc.

This patch *does* revert some changes which have occurred upstream since
3.6; these will be re-applied as apppropriate on top of this new base.
