Adds bluestore-specific options related to the metadata-only journal.

The options allow a user to control:

1. path to a bluestore wal (block special file or regular file)
2. path to a bluestore db (block special file or regular file)
3. size of both

Their configuration works similarly to the FileStore journal. If paths
are not specified both WAL and DB will be collocated on the same block
device as data.

Other options can be configured via an existing config-flags option if needed.

Bionic, being the next LTS, is important to enable for dev
and test as early as possible ahead of 18.02.

Zesty goes EOL in Jan 2018. The next stable charms release (18.02)
will not provide Zesty series support, as it was an interim
(non-LTS) release.

Juju and configuration provided bucket keys to
'default-{row,rack}' ensuring that keys are unique.

The blacklist actions allow for adding and removing devices
to a unit-local list of devices to be skipped during osd
initialization. This list will be used to override the
application level, and thereby deployment wide, 'osd-devices'
configuration option on a individual unit basis.

The pre-existing list-disk action is extended to return
list of blacklisted devices under the 'blacklist' key.

Upstream Ceph removed the `osd crush location` option in
commit f9db479a14d9103a2b7c0a24d958fe5fff94100e [0]. This
causes new clusters deployed from the Pike UCA (Luminous)
using the customize-failure-domain option to not create or
move the OSD to the correct spot in the OSD tree. The end
result is that placement groups will fail to peer because
there are no racks to select hosts and OSDs from.

Instead, the charm should set the more generic `crush
location` option in the ceph.conf file. It is and has been
supported since the Firefly (trusty-icehouse) version of
Ceph.

During ceph to ceph-osd/ceph-mon migrations, the bootstrap keyring
for the cluster will be in place as the ceph-osd units are started
alongside existing ceph units.

Switch this check to look for the upgrade keyring, which won't be
in place until the ceph-osd <-> ceph-mon relation is complete, at
which point in time a) the unit has the correct access to perform
the upgrade and b) the previous/current version check code will
not trip over due to the previous value of the source option
being None, resulting in a fallback to 'distro' as the previous
source of ceph.

Essentially, we want to avoid doing:

    from module import f1, f2, f2

and instead doL

    import module

    module.f1()

This helps with reading the code and understanding where the functions
come from.

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.
