* 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

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.

We don't use pool ID 0 any more because CephFS can't handle it.
Update the user quick-start to include it, and add some links to support that process.
Fix the tests to handle the new state of life.

Store a random value up to the filestore_split_rand_factor for each
collection when it is created or apply-layout-settings is run. This
should help distribute the load of splitting directories across a
longer period of time.

DOUT_COND was obsoleted by f41887e38d.
Balancer and Mantle use a dout hack to continue working since we will probably
specifically want very verbose balancer output in the future.

Creates an installable version of "src/include/rados/objclass.h" that allows
object classes to be built outside of the Ceph tree. cls_sdk is an example
of such an object class.

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).
