    mds: create snaprealm for quota enabled inode

    this simplifies client code for find quota enabled inode

    Signed-off-by: "Yan, Zheng" <zyan@redhat.com>

We now use SnapRealms to manage quotas. Zheng, after thinking about this more I'm not sure if a compatibility flag will make sense for older clients. Should we prevent older clients from writing to directories with quotas if they do not know how to enforce the quota?

We also need to consider a feature flag (require_mimic_mds) for MDS upgrades. What do you think?
