Joshua Boniface 526a5f4a74 Add support for split OSD adds
Allows creating multiple OSDs on a single (NVMe) block device,
leveraging the "ceph-volume lvm batch" command. Replaces the previous
method of creating OSDs.

Also adds a new ZK item for each OSD indicating if it is split or not.

Joshua Boniface a0b45a2bcd Always create RBDs with bytes value
Converting into human results in imprecise values when specifying bytes
directly, which in turn breaks VMDK image uploads. Instead, just use the
raw bytes value when creating the volume instead of converting it back.

Joshua Boniface 7a40c7a55b Add support for replacing/refreshing OSDs
Adds commands to both replace an OSD disk, and refresh (reimport) an
existing OSD disk on a new node. This handles the cases where an OSD
disk should be replaced (either due to upgrades or failures) or where a
node is rebuilt in-place and an existing OSD must be re-imported to it.

This should avoid the need to do a full remove/add sequence for either
case.

Also cleans up some aspects of OSD removal that are identical between
methods (e.g. using safe-to-destroy and sleeping after stopping) and
fixes a bug if an OSD does not truly exist when the daemon starts up.

Joshua Boniface 4d698be34b Add OSD removal force option
Ensures a removal can continue even in situations where some step(s)
might fail, for instance removing an obsolete OSD from a replaced node.

Joshua Boniface 1142454934 Add pool PGs count modification
Allows an administrator to adjust the PG count of a given pool. This can
be used to increase the PGs (for example after adding more OSDs) or
decrease it (to remove OSDs, reduce CPU load, etc.).

Joshua Boniface 25fe45dd28 Add device class tiers to Ceph pools
Allows specifying a particular device class ("tier") for a given pool,
for instance SSD-only or NVMe-only. This is implemented with Crush
rules on the Ceph side, and via an additional new key in the pool
Zookeeper schema which is defaulted to "default".

Joshua Boniface 6ccd19e636 Standardize fuzzy matching and use fullmatch
Solves two problems:

1. How match fuzziness was used was very inconsistent; make them all the
same, i.e. "if is_fuzzy and limit, apply .* to both sides".

2. Use re.fullmatch instead of re.match to ensure exact matching of the
regex to the value. Without fuzziness, this would sometimes cause
inconsistent behavior, for instance if a limit was non-fuzzy "vm",
expecting to match the actual "vm", but also matching "vm1" too.

Joshua Boniface 65df807b09 Add support for configurable OSD DB ratios
The default of 0.05 (5%) is likely ideal in the initial implementation,
but allow this to be set explicitly for maximum flexibility in
space-constrained or performance-critical use-cases.

Joshua Boniface adc8a5a3bc Add separate OSD DB device support
Adds in three parts:

1. Create an API endpoint to create OSD DB volume groups on a device.
Passed through to the node via the same command pipeline as
creating/removing OSDs, and creates a volume group with a fixed name
(osd-db).

2. Adds API support for specifying whether or not to use this DB volume
group when creating a new OSD via the "ext_db" flag. Naming and sizing
is fixed for simplicity and based on Ceph recommendations (5% of OSD
size). The Zookeeper schema tracks the block device to use during
removal.

3. Adds CLI support for the new and modified API endpoints, as well as
displaying the block device and DB block device in the OSD list.

While I debated supporting adding a DB device to an existing OSD, in
practice this ended up being a very complex operation involving stopping
the OSD and setting some options, so this is not supported; this can be
specified during OSD creation only.

Closes #142

Joshua Boniface 73e8149cb0 Remove explicit image-features from rbd cmd
This should be managed in ceph.conf with the `rbd default
features` configuration option instead, and thus can be tailored to the
underlying OS version.

Joshua Boniface 4a7246b8c0 Ensure RBD resize has bytes appended
If this isn't, the resize will be interpreted as a MB value and result
in an absurdly big volume instead. This is the same consistency
validation that occurs on add.

Joshua Boniface dc03e95bbf Ensure consistent sizing of volumes
Convert from human to bytes, then to megabytes and always pass this to
the RBD command. This ensures consistency regardless of what is actually
passed by the user.

This reverts commit 00e9cca6f0.

This causes RBD mapping to fail on Debian 10. Reverting but keeping in
history for future reference.

Joshua Boniface 9291ce6ffc Correct output of fromhuman and add size compare
Ensures that the bytes_tohuman returns an integer to avoid the hacky
workaround of stripping off the B.

Adds a verification on the size of a new volume, that it is not larger
than the free space of the pool to prevent errors/excessively-large
volumes from being created.
