glusterd/quota: upgrade quota.conf file during an upgrade
Problem
=======
When quota is enabled on 3.6, it will have quota conf version in quota.conf
as v1.1. This node gets upgraded to 3.7 but it will still have quota conf
version as v1.1 until a quota enable/disable/set limit is initiated. When
this is not initiated and when this node tries to peer probe a node which
is a fresh install of 3.7 (which will have quota conf version as v1.2), then this
will result in "Peer rejected" state. This patch fixes the issue.
Solution
========
When an upgrade happens from 3.6 to 3.7, quota.conf file needs
to be modified as well. With 3.6, in quota.conf the version will be
v1.1 and it needs to be changed to v1.2 from 3.7. This is because in
3.7, inode quota feature is introduced. So when an op-version bumpup
happens quota.conf needs to be upgraded with quota conf version v1.2
and all the 16 byte uuid needs to be changed to 17 bytes uuid as well.
Previously, when the cluster version is upgraded to 3.7, the quota.conf
got upgraded as well. But, the upgradation was done only when quota
enable/disable/set limit is done. With this patch, the upgradation is done
during a cluster op version bump up as well.
