xie xingguo d792e8d528 crush: "osd crush class rename" support 
In 076a6abd80 I killed the 'class rename' command
and thought it was totally useless but I was wrong.

Consider the following user case:
(1) randomly choose some OSDs(e.g., from different hosts) and try to make them for private use only,
    say, by grouping them into 'pool1'
(2) ceph osd crush set-device-class pool1 'OSDs from (1)'
(3) ceph osd crush rule create-replicated rule_for_pool1 default host pool1
(4) ceph osd pool rename pool1 pool2
(5) ceph osd crush class rename pool1 pool2

From the above user case, we need to safely change a pool name without worrying
any risk of data migration. That is why the 'osd crush class rename' command
is still needed here.

qa/standalone
=============

These scripts run standalone clusters, but not in a normal way.  They make
use of functions ceph-helpers.sh to quickly start/stop daemons against
toy clusters in a single directory.

They are normally run via teuthology based on qa/suites/rados/standalone/*.yaml.

You can run them in a git checkout + build directory as well:

  * The qa/run-standalone.sh will run all of them in sequence.  This is slow
     since there is no parallelism.

  * You can run an individual script by passing these environment args.  For
    example, if you are in the build/ directory,

PATH=$PATH:bin CEPH_ROOT=.. CEPH_LIB=lib ../qa/standalone/mon/misc.sh
