- libgfchangelog is simplified by removing unnecessary API Class
- Merged Agent logic into Worker instead of running Worker and Agent as
  two separate processes and maintaining RPC between Worker and Agent.
- Geo-rep command Pause and Resume will continue without any changes.
  But Agent functionality also gets paused with that.

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.

All the workers connects to primary slave node. It should
connect to available slave nodes in round robin fashion
and choose different slave node if the corresponding slave
node is down. This patch fixes the same.

Thanks Aravinda for the help in root causing this.

Updates: bz#1737484

`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
