d8269b0819 doc/dev/osd_internals:manifest.rst: clarification for manifest design and future steps 
I've added a few significant changes:
* TIER_PROMOTE purely ensures that data is resident in the base pool
* Add EVICT_CHUNK to permit a tiering agent to selectively cold space
  from HEAD/snapshots independently of SET_CHUNK.
* Avoid using DIRTY entirely for dedup targets.
* Instead of modifying clone_range when updating clone manifests, simply
  update ReplicatedBackend::calc_*_subsets to also consider the clone
  obc manifest.

I've also added sections on how tiering agents are rbd/rgw are meant
to interact as well as on testing.

b3e1c58b0e osd: Replace active/pending scrub tracking for local/remote 
This is similar to how recovery reservations are split between
local and remote.

It was the case that scrubs_pending was used for reservations at
the replicas as well as at the primary while requesting reservations
from the replicas.  There was no need for scrubs_pending to turn
into scrubs_active at the primary as nothing treated that value
as special.  scrubber.active = true when scrubbing is
actually going.

Now scurbber.local_reserved indicates scrubs_local incremented
Now scrubber.remote_reserved indicates scrubs_remote incremented

5e36acdb6f osd/: mechanically rename RecoveryMachine/State/Ctx to Peering* 
I'm going to extract this logic and reuse it in crimson.  Recovery* has
always been a confusing name as it implements neither log-based recovery
nor backfill.  Rather, it's mainly the buisiness logic for agreeing on
an authoritative log and some ancillary things such as scrub/backfill
reservation.

$ for i in $(git grep -l 'RecoveryMachine'); do sed -i 's/RecoveryMachine/PeeringMachine/g' $i; done
$ for i in $(git grep -l 'RecoveryState'); do sed -i 's/RecoveryState/PeeringState/g' $i; done
$ for i in $(git grep -l 'RecoveryCtx'); do sed -i 's/RecoveryCtx/PeeringCtx/g' $i; done

dc7a2aaf7a erasure-code: ruleset-* -> crush-* 
1) ruleset is an obsolete term, and
2) crush-{rule,failure-domain,...} is more descriptive.

Note that we are changing the names of the erasure code profile keys
from ruleset-* to crush-*.  We will update this on upgrade when the
luminous flag is set, but that means that during mon upgrade you cannot
create EC pools that use these fields.

When the upgrade completes (users sets require_osd_release = luminous)
existing ec profiles are updated automatically.
