+++ This bug was initially created as a clone of Bug #1339054 +++

Description of problem:
======================
If we try to remove offline brick, the operation is failing with error message
"volume remove-brick start: failed: Found stopped brick
<hostname>:/bricks/brick1/a1" and this condition is added newly in 3.7.9-6
build.

Currently we have use force option to remove the offline brick and same thing
is expected in the failure message to use force option to remove the offline
brick to guide the user.

With this users will know the how to remove the offline brick.


Version-Release number of selected component (if applicable):
=============================================================
glusterfs-3.7.9-6


How reproducible:
=================
Always


Steps to Reproduce:
===================
1. Create a simple volume of any type and start it
2. Kill one of the volume brick
3. Try to remove the killed brick (offline brick) 
4. Check the brick failure error message //message won't convey how to remove
the brick.


Failure message getting:
=======================
]# gluster volume remove-brick Dis <hostname>:/bricks/brick1/a1 start
volume remove-brick start: failed: Found stopped brick
<hostname>:/bricks/brick1/a1


Actual results:
================
Failure is not saying how to remove the offline brick.

Expected results:
=================
Failure message need to have force option help message to remove the offline
brick.
