[Shrivaibavi]

Description:
When triggered gd1 testcases by using gd2 libraries we identified few gaps in the gd2 libraries.
I hereby list the following libraries needed to be implemented in gd2

1. peer_detach_servers
   2.peer_probe_servers
   3.is_peer_connected
   4.get_snapshot_info_by_volumename
   5.Brick libs needs to implemented( form_brick_list etc)
   6.snapshot_list_by_volname
   7.volume_exists
   8.setup_volume
   9.cleanup_volume

Note: The libraries implemented till now are under review and we are working to get them merged as soon as possible.

I request this to be broken into separate issues (as enhancement/rfe) for better tracking and closure.

@Shrivaibavi - Haven't heard back on the closure of this issue.
@Akarsha-rai - Have we fixed the issues mentioned in the description as part of latest code base.

@rhinduja All the libraries mentioned in the issue are implemented and patches are under review except for the snapshot operations serial number 4 & 6 as they are not implemented in gd2 and lower priority as of now.
