Description SATHEESARAN 2020-07-20 08:05:35 UTC 
Description of problem:
------------------------
Geo-rep prerequisites needs to be updates.
1. Only one geo-replicated volume is no longer the restriction. So that point should be removed - "One geo-replicated volume only"
2. Instead of the above mention the requirement to configure geo-rep session manually from the node using gluster CLI commands.

Expected results:
--------------------
Update the section 3.11.1 

1. only one geo-rep volume is not a prerequisite any more
2. add prereq to create geo-rep session from gluster CLI
