+++ This bug was initially created as a clone of Bug #1223739 +++

There is change in quota.conf format in release-3.7. In a heterogeneous cluster
if the quota limit is changed, this can cause a hand-shake problem when
glusterd is restarted.

Do not allow setting/removing quota limit in heterogeneous cluster

    quota: quota.conf backward compatibility fix

    In release-3.7 the format of quota.conf is changed.
    There is a backward compatibility issues during upgrade
    1) There can be an issue when peer sync between node-3.6 and node-3.7
    2) If the user sets/removes limit, there is will different format of
       file in node-3.6 and node-3.7

    This patch fixes the issue:
    1) restrict the user to execute command quota enable, limit-usage, remove
    2) write quota.conf in older format if op-version is less than 3.6
