geo-rep test failure with https://github.com/gluster/glusterfs/pull/2945

[Shwetha-Acharya]

All the geo-replication tests have a pre-requisite of passwordless ssh connection establishment, which is being handled by infra.

however, with gluster/glusterfs#2945 the localhost and the loopback address(127.0.0.1) are replaced with valid ipv4 address, obtained by the command #ip -o -4 addr | grep -v "\<lo\>" | awk '{print $4}' | cut -d/ -f1

Hence the previously setup password-less with the loopback/localhost address is not working for any of the root geo-rep tests.

Please setup a password-less connection with the ip addresses obtained from the command:
#ip -o -4 addr | grep -v "\<lo\>" | awk '{print $4}' | cut -d/ -f1
