v0.70
~~~~~
mds: disable adding snapshots by default. (re-enable them with "ceph mds allow_snaps")
MDS: lock out snapshots until after a flag has been set in the MDSMap This way users can't put snapshots on their clusters unless they explicitly ask for them and have seen a warning message. We take a bit of the MDSMap flags in order to do so. The only thing a little weird here is that anybody who upgrades to this patch who already has snapshots will hit the EPERM and have to go through the warning, but it doesn't impact existing snapshots at all so they should be good. To go along with this, we add "ever_allowed_snaps" and "explicitly_allowed_snaps" members to the MDSMap, which are default to false and are set to true when allow_new_snaps is set. Old maps decoded with new code default to true and false, respectively, so we can tell.
