If provided, set the OSD device_class at OSD creation time. This is
simpler than writing a file that the OSD has to read in and use to
set its initial device class, and also avoids a bit of sticky state
at the OSD that will make it keep trying to reset its device class on
startup if it ever gets cleared.
Note that we now ignore json input fields we don't understand, so remove
a test case.

Since kraken, Ceph enforces a 1:1 correspondence between CRUSH ruleset and
CRUSH rule, so effectively ruleset and rule are the same thing, although
the term "ruleset" still survives - notably in the CRUSH rule itself, where it
effectively denotes the number of the rule.
This commit updates the documentation to more faithfully reflect the current
state of the code.

Though "ls" command is explained and it's usage shown in the man page,
it is not mentioned in the subcommands list of "ceph osd" in the
beginning.

`ceph rmfailed` refers to its argument as "who" and `ceph repaired` refers to its argument as "rank". We should make these commands and others consistent by standardizing the argument as "role".

An osd is safe to destroy if
- we have osd_stat for it
- osd_stat indicates no pgs stored
- all pgs are known
- no pgs map to it
An osd is ok ot stop if
- we have pg stats
- no pgs will drop below min_size

* 8/ceph.rst: `rm` subcommand removes osd from osdmap, not the cluster.
the latter is more ambiguous in different contexts.
* rados/operations/add-or-rm-osds.rst: add a subsection of "Replacing an
OSD". update the subsection of "Removing the OSD" with "ceph osd
purge" command
* release-notes.rst: link from it to the new subsection in add-or-rm-osds.rst

With the introduction of `osd new`, we are now deprecating `osd create`
with the intent of removing it in a future release.

The man page did not prepare the user for the fact that "ceph quorum exit" will
cause a random monitor to leave quorum, nor did it say explicitly how to make
the command work on a specific monitor.

This is a dev hack to generate a bunch of bogus osdmaps. The maps are
all screwed up anyway (e.g., invalid addrs) and this is minimally useful.

This mostly is just removing the commands from the man page ceph(1). I
left the legacy section in doc/cephfs/administration.rst as-is.

Add a --no-increasing option to reweight-by-* which can be used to only decrease
OSD weights without increasing any. This is useful for example if you need to
urgently lower the weight of nearly full OSDs.
Also add a --yes-i-really-mean-it confirmation to reweight-by-*.

sphinx requires that a document tree to be in a single directory,
and the man pages are references by our document. so a simple solution
would be to put all the rst file under a single directory.
