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.).
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".
Allows specifying blockdevs in the OSD and OSD-DB addition commands as
detect strings rather than actual block device paths. This provides
greater flexibility for automation with pvcbootstrapd (which originates
the concept of detect strings) and in general usage as well.
This ensures that any client command is logged by the local system.
Helps ensure Accounting for users of the CLI. Currently logs the full
command executed along with the $USER environment variable contents.
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.
This is recommended by the Python Requests documentation:
> It’s a good practice to set connect timeouts to slightly larger than a
multiple of 3, which is the default TCP packet retransmission window.
This allows us to keep a very low connect timeout of 3 seconds, but also
ensure that long commands (e.g. --wait or VM disable) can take as long
as the API requires to complete.
Avoids having to explicitly set very long single-instance timeouts for
other functions which would block forever on an unreachable API.
The Ansible manual can't keep up with the other repo, so it should live
there instead (eventually, after significant rewrites).
The Testing page is obsoleted by the "test-cluster" script.
Allows preserving colour within e.g. watch, where Click would normally
determine that it is "not a terminal". This is done via the wrapper echo
which filters via the local config.
Remove the prepare script, and run the two stages manually. Better
handle Black reformatting by doing a check (for the errcode) then
reformat and abort commit to review.
Instead of requiring the VM to already be stopped, instead allow disable
state changes to perform a shutdown first. Also add a force option which
will do a hard stop instead of a shutdown.

Make sure all of these move to the root of the repository first, then
return to where they were afterwards, using pushd/popd. This allows them
to be executed from anywhere in the repo.
