Description of problem:
When you bind glusterd to a specific IP, shd operates correctly but the 'vol replace-brick' command attempts to contact glusterd on 127.0.0.1 and fails.

Version-Release number of selected component (if applicable):
glusterfs 3.7.x (and prior releases?)

How reproducible:
Every time! I noticed this in a test environment I'm using for containers, where I bind glusterd host IP.

Steps to Reproduce:
1. use transport.socket.bind-address to bind glusterd to a specific IP on each host
2.volume replace-brick <VOLNAME> <SOURCE-BRICK> <NEW-BRICK> {commit force}

Actual results:

Expected results:
vol replace-brick should work whether glusterd is bound to a specific IP or not

Additional info:
The issue has been discussed with Ravi (ravishankar) and Humble (hchiramm) and identified as localhost being hardcoded.
