Description of problem:
======================
as per admin guide of 3.4 in section 5.6.1( https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.4/html-single/administration_guide/index#sect-Creating_Replicated_Volumes ) we clearly state that creation of new x2 replica volumes stands deprecated.

We must hence change the warning in CLI to reflect the same.


currently we are getting below warning:

[root@dhcp35-190 ~]# gluster v create rep rep 2 dhcp35-237.lab.eng.blr.redhat.com:/gluster/brick1/rep2 $HOSTNAME:/gluster/brick1/rep2
Replica 2 volumes are prone to split-brain. Use Arbiter or Replica 3 to avoid this.
Do you still want to continue?
 (y/n) 



Need to change it to something like below:
*CREATION OF A NEW REPLICA 2 VOLUME STANDS DEPRECATED*  as they are prone to split-brain. Use Arbiter or Replica 3 to avoid this.

Do you still want to continue ?
 (y/n)

Version-Release number of selected component (if applicable):
=============
