Problem:

Geo-rep session for non-root going faulty.

Solution:

During worker start we do not construct slave url and use 'args.resource_remote'
which is basically just slave-hostname.
This works better for root session but fails in non-root session during
ssh command.
Using slave url solves this issue.

`address_family=inet6` needs to be added while mounting master and
slave volumes in gverify script.

New option introduced to gluster cli(`--inet6`) which will be used
internally by geo-rep while calling `gluster volume info
--remote-host=<ipv6>`.

The file objects for python3 by default is opened
in binary mode where as in python2 it's opened
as text by default.

The geo-rep code parses the output of Popen assuming
it as text, hence used the 'universal_newlines' flag
which provides backward compatibility for the same.

This patch adds version agnostic imports for urllib, cpickle,
socketserver, _thread, queue, etc., suggested by Aravinda in
https://review.gluster.org/#/c/19767/1

Note: Fedora packaging guidelines require explicit shebangs, so
popular practices like #!/usr/bin/env python and #!/usr/bin/python
are not allowed; they must be #!/usr/bin/python2 or #!/usr/bin/python3

Note: Selected small fixes from 2to3 utility. Specifically apply,
basestring, funcattrs, idioms, numliterals, set_literal, types, urllib,
and zip have already been applied.

For Glusterd2 integration, JSON output of status and config
is very useful from gsyncd

- Fixed Python pep8 issues
- Removed dead code
- Rewritten configuration management
- Rewritten Arguments/subcommands handling
- Added Args upgrade to accommodate all these changes without changing
  glusterd code
- use of md5 removed, which was used to hash the brick path for workdir

Both Master and Slave nodes will have subdir for session in the
format "<mastervol>_<primary_slave_host>_<slavevol>

  $GLUSTER_LOGDIR/geo-replication/<mastervol>_<primary_slave_host>_<slavevol>
  $GLUSTER_LOGDIR/geo-replication-slaves/<mastervol>_<primary_slave_host>_<slavevol>

Log file paths renamed since session info is available with directory
name itself.

  $LOG_DIR_MASTER/
      - gsyncd.log - Gsyncd, Worker monitor logs
      - mnt-<brick-path>.log - Aux mount logs, mounted by each worker
      - changes-<brick-path>.log - Changelog related logs(One per brick)

  $LOG_DIR_SLAVE/
      - gsyncd.log - Slave Gsyncd logs
      - mnt-<master-node>-<master-brick-path>.log - Aux mount logs,
        mounted for each connection from master-node:master-brick
      - mnt-mbr-<master-node>-<master-brick-path>.log - Same as above,
        but mountbroker setup
