Description of problem:

With older versions of gluster, say 3.5.3, glusterfs supports setting selinux
context over fuse.glusterfs mountpoint. After 3.6.1, it throws an error :
"Invalid option: context". 

The problem is because of a change in mount.glusterfs script. With older
versions, it works fine.

Version-Release number of selected component (if applicable):


How reproducible:
Always in versions from 3.6

Steps to Reproduce:
http://www.gluster.org/pipermail/gluster-users.old/2015-January/020014.html

Actual results:
It throws an error "Invalid option: context"

Expected results:
Inform FUSE that the glusterfs sub-filesystem supports SElinux while passing
mount options and allow to set selinux context over the mountpoint.


Additional info:

When you set selinux context, the same can be verfied in /proc/mounts:

vm1:sel /qwe1 fuse.glusterfs
rw,context=system_u:object_r:user_home_t:s0,relatime,user_id=0,group_id=0,default_
   permissions,allow_other,max_read=131072 0 0
