This reverts commit 3189ba19a7, reversing
changes made to b7620de020.
Despite the change in json format being positive, the unfortunate side-effect
is that it broke upgrade testing (because the QA framework must handle the
transition of mdsmap["info"] to a list from object) and the ceph-mgr.

These configs were used for initialization but it is more appropriate to
require setting these file system attributes via `ceph fs set`. This is similar
to what was already done with max_mds. There are new variables added for `fs
set` where missing.

Check total pg count for the cluster vs osd count and max pgs per osd
before allowing pool creation, pg_num change, or pool size change.
"in" OSDs are the ones we distribute data too, so this should be the right
count to use. (Whether they happen to be up or down at the moment is
incidental.)
If the user really wants to create the pool, they can change the
configurable limit.

This introduces two config parameters:
mds_cache_memory_limit: Sets the soft maximum of the cache to the given
byte count. (Like mds_cache_size, this doesn't actually limit the maximum
size of the cache. It just dictates the steady-state size.)
mds_cache_reservation: This replaces mds_health_cache_threshold everywhere
except the Beacon heartbeat sent to the mons. The idea here is to specify a
reservation of memory (5% by default) for operations and the MDS tries to
always maintain that reservation. So, the MDS will recall caps from clients
when it begins dipping into its reservation of memory.
mds_cache_size still limits the cache by Inode count but is now by-default 0
(i.e. unlimited). The new preferred way of specifying cache limits is by memory
size. The default is 1GB.

Reordered the RC releases sections back to their respective components,
added a ceph-mon section, added links to documentation wherever
possible, and a few forgotten RGW announcements. Also cleared up the
PendingReleaseNotes upto this point

Also cleanup PendingReleasenotes to an empty file so that only newer
changes are tracked, adding the relevant section back to
RC1 where relevant. Moving all the RC1 announcements back to RC2, when
we go to 12.2.0 we'll collapse all of these back to the release
announcments

This has a few problems:
1- It does not do it's analysis over CRUSH rule roots/classes, which
means that an innocent user of classes will see skewed usage (bc hdds are
more full than ssds, say)
2- It does not take degraded clusters into account, which means the warning
will appear when a fresh OSD is added.

It's still sort of awkward to prefix these commands
with "mgr tell" but this makes them at least
somewhat accessible to the average user.

Make an incompat change here with a release note since
this only affects pool creation, a rare event, and folks
who have customized their configs (also rare).
Keep it simple: a config sets the default rule, or else we pick
the first TYPE_REPLICATED pool in the crush map.

- rename the option (max -> warn)
- add an err_..._ratio multiplier
- switch to HEALTH_ERR once requests are blocked long enough
- make the error ratio high (default is 32*128s -> about an hour) so that
we don't trigger on a heavily loaded cluster.
