rbd_list will return -ENOENT when no rbd_directory object
exists. Handle this in the cli tool and interpret it as success with
an empty list.
Add this to the release notes since it changes command line behavior.

--osd-pool-default-crush-replicated-ruleset replaces
--osd-pool-default-crush-rule
If --osd-pool-default-crush-rule is set it takes precedence over
--osd-pool-default-crush-replicated-ruleset and a deprecation warning is
displayed.
The CrushWrapper::get_osd_pool_default_crush_replicated_ruleset helper is
used to implement this behaviour.

Note that a bunch of stuff we thought would go in 0.70 is actually in 0.69,
so the update/release notes were adjusted accordingly.

This is incomplete and unfortunately unusable in its current state:
- it would only set USES_TMAP for old encoded object_info_t and tmapput,
but would NOT set it for tmapup
- a config option turned that off by default.
That means that the mds conversion from tmap -> omap won't be able to use
this because any existing cluster has tmap objects without the USES_TMAP
flag set. And we don't want to unconditionally try a tmap->omap conversion
on omap operations because there are lots of existing librados users out
there that will be negatively impacted by this.
Instead, the MDS will need to handle this conversion on the client side by
reading either tmap or omap objects and explicitly rewriting the content
with omap (while truncating the tmap data away).
The auto-conversion function was added in v0.44.

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.

The C++ AioCompletion::get_version() method only returns 32-bits. Sigh.
Add a get_version64() method that returns all 64-bits. Do not touch the
32-bit version to avoid breaking the ABI.

This method is problematic because it both writes/mutates and returns data,
which means that an untimely client disconnect or peering event will result
in a success to the client with no payload.
It has not been used since v0.52 (18054ba46f)
which is pre-bobtail; so this change breaks compatibility with pre-bobtail
librbd clients (at least for image creation).

The previous 'osd scrub min interval' was mostly meaningless and useless.
Meanwhile, the 'osd scrub max interval' would only trigger a scrub if the
load was sufficiently low; if it was high, the PG might *never* scrub.
Instead, make the 'min' what the max used to be. If it has been more than
this many seconds, and the load is low, scrub. And add an additional
condition that if it has been more than the max threshold, scrub the PG
no matter what--regardless of the load.
Note that this does not change the default scrub interval for less-loaded
clusters, but it *does* change the meaning of existing config options.
