In small clusters, adding OSDs at their full weight causes massive IO
workload which makes performance unacceptable.  This adds a config
option to change the initial weight, we can set it to 0 or something
small for clusters that would be affected.

Add highly experimental support for bluestore storage format for
OSD devices; this is disabled by default and should only be enabled
in deployments where loss of data does not present a problem!

Some upgrade scenarios (hammer->jewel) require that the ownership
of the ceph osd directories are changed from root:root to ceph:ceph.
This patch improves the upgrade experience by upgrading one OSD at
a time as opposed to stopping all services, changing file ownership,
and then restarting all services at once.

This patch makes use of the `setuser match path` directive in the
ceph.conf, which causes the ceph daemon to start as the owner of the
OSD's root directory. This allows the ceph OSDs to continue running
should an unforeseen incident occur as part of this upgrade.

This patch starts down the road to automated performance
tuning.  It attempts to identify optimal settings for
hard drives and network cards and then persist them
for reboots.  It is conservative but configurable via
config.yaml settings.

Adds a new config-flags option to the charm that
supports setting a dictionary of ceph configuration
settings that will be applied to ceph.conf.

This implementation supports config sections so that
settings can be applied to any section supported by
the ceph.conf template in the charm.

As of the Ceph Jewel release, certain limitations apply to
OSD object name lengths: specifically if ext4 is in use for
block devices or a directory based OSD is configured, OSD's
must be configured to limit object name length:

  osd max object name len = 256
  osd max object namespace len = 64

This may cause problems storing objects with long names via
the ceph-radosgw charm or for direct users of RADOS.

Also ensure that ceph.conf as a final newline as ceph requires
this.

This reverts commit c94e0b4b.

Support for juju provided zones was broken on older Ceph releases
where MAAS zones are not configured (i.e. nothing other than the
default zone).

Backing this change out until we can provide a more complete and
backwards compatible solution.

This change adds functionality to allow the ceph osd cluster to
upgrade in a serial rolled fashion.  This will use the ceph monitor
cluster to lock and allows only 1 ceph osd server at a time to upgrade.
The upgrade is initiated setting a config value for source for the
service which will prompt the osd cluster to upgrade to that new
source and restart all osds processes server by server.  If an osd
server has been waiting on a previous server for more than 10 minutes
and hasn't seen it finish it will assume it died during the upgrade
and proceed with its own upgrade.

I had to modify the amulet test slightly to use the ceph-mon charm
instead of the default ceph charm.  I also changed the test so that
it uses 3 ceph-osd servers instead of 1.

Limtations of this patch: If the osd failure domain has been set to osd
than this patch will cause brief temporary outages while osd processes
are being restarted.  Future work will handle this case.

This reverts commit db09fdce.

The approach here is to use the availability zone as an imaginary rack.
All hosts that are in the same AZ will be in the same imaginary rack.
From Ceph's perspective this doesn't matter as it's just a bucket after all.
This will give users the ability to further customize their ceph deployment.
