[lib] Add functionality to setup master and slave volumes

Adding the code for the following:
1.Adding function setup_master_and_slave_volumes() to geo_rep_libs.
2.Adding variables for master_mounts, slave_mounts, master_volume
  and slave_volume to gluster_base_class.py
3.Adding class class method
  setup_and_mount_geo_rep_master_and_slave_volumes to
  gluster_base_class.py.
