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.

6f8e4b3810 src: rename ReplicatedPG to PrimaryLogPG 
It's been confusing for a long time that EC pools are implemented by
ReplicatedPG.  What PG/ReplicatedPG really implement is the concept
of a PG where consistency is managed by the primary via a log.

487105df10 erasure-code: add directory to plugin init functions 
The prototype of the init functions of erasure coded plugins is changed
from

   int __erasure_code_init(char *plugin_name)

to

   int __erasure_code_init(char *plugin_name, char *directory)

The jerasure plugin will find optimized variants in this directory and
load them. The load() and preload() functions of
ErasureCodePluginRegistry only use a directory instead of a more generic
parameters map. The parameters map was only used for the directory entry
anyway.
