Subject: [PATCH 515/525] index: Do not proceed with init if brick is not
 mounted

Backport of: https://review.gluster.org/17426

..or else when a volume start force is given, we end up creating
/brick-path/.glusterfs/indices folder and various subdirs under it and
eventually starting the brick process.

As a part of this patch, glusterd_get_index_basepath() is added in
glusterd, who will then use it to create the basepath during
volume-create, add-brick, replace-brick and reset-brick. It also uses this
function to set the 'index-base' xlator option for the index translator.
