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.

This is used to dump extra weirdness to the health detail structured
output, but we are about to remove all of that in luminous.

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.

This is undocumented and untested -- it was something
written before and superceded by the "recover_dentries"
subcommand. While we're at it, also
s/scavenge_dentries/recover_dentries/
internally.

- 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.

With bluestore, making the smallest write match min_alloc_size avoids
write amplification. With EC pools this is the stripe unit, or
stripe_width / num_data_chunks. Rather than requiring people to divide
by k to get the smallest ec write, allow it to be specified directly
via stripe_unit. Store it in the ec profile so changing a monitor
config option isn't necessary to set it.
This is particularly important for ec overwrites since they allow random i/o
which should match bluestore's checksum granularity (aka min_alloc_size).

This had been broken for some time, as since the new
JournalStream stuff, zero padding was no longer a valid
encoding.

In practice this tends to get bubbled up the stack as an error on
the caller, and they usually do not handle it properly. For example,
with librbd, this turns into EIO and break the VM.
Instead, this will manifest as a hung op on the client. That is
also not ideal, but given that the root cause here is generally a
bug, it's not clear what else would be better.
We already log an error in the cluster log, so teuthology runs will
continue to fail.

Expose public methods that include a new output argument to indicate

This change does prioritize backfill of PGs which don't
have min_size active copies. Such PGs would cause IO stalls
for clients and would increase throttlers usage.
This change also fixes few subtlle out-of-bounds bugs.
