Description of problem:
-----------------------

I can set the value of cluster.brick-multiplex to literally anything.

ONLY boolean values should be set for the tunable.


* set to a random string of chars* :

[root@gqas009 ~]# 
[root@gqas009 ~]# gluster v set all cluster.brick-multiplex  fe
volume set: success
