Joshua Boniface c5ec0f4f62 Add updated tuning configuration
Uses a much nicer CPU tuning configuration, leveraging systemd's
AllowedCPUs and CPUAffinity options within a set of slices (some
default, some custom).

Configuration is also greatly simplified versus the previous
implementation, simply asking for a number of CPUS for both the system
and OSDs, and calculating everything else that is required.

Also switches (back) to the v2 unified cgroup hierarchy by default as
required by the systemd AllowedCPUs directive.

Joshua Boniface 7d329708bc Remove cpuset configurations
This functionality simply did not work, with Libvirt continuing to dump
its processes into the root cset thus defeating the purpose entirely.

Just remove it, from some very initial testing it isn't worth the
headache.

Joshua Boniface 503a2e6c0b Remove pvc-flush references
This service causes more problems than it solves usually, so it is being
removed in the next PVC version.

Joshua Boniface 87ae5a12e9 Add Ceph support for single-node clusters
Ensures that the pool default size/min size is set to something
reasonable for a single node (effective RAID-1) and replace teh default
CRUSH replicate_rule set for this situation with one choosing OSD
instead of host as the default.

Joshua Boniface bea79b5102 Add immutability to PVC subrole
1. Remove the obsolete pvc-vacuum script install.

2. Remove notifies when modifying configs; we do not want to restart the
daemons uncontrolled.

3. Add bootstrap check to package installs so they only happen on
bootstrap.

This ensures this part of the role, on re-runs, will *only* update
configs and not actually touch the running daemon. This makes it safe to
run before a oneshot/update-pvc-daemons.yml playbook run.

Joshua Boniface 414678f683 Fix a few more extraneous splits
Just use this_node if applicable, or the raw node.hostname.

Joshua Boniface b24e539252 Remove extraneous splits
The node.hostname should always be short.

Joshua Boniface 243c910d6d Unify and standardize inventory_hostname
This was causing some confusing conflicts, so create a new fact called
"this_node" which is inventory_hostname.split('.')[0], i.e. the short
name, and use that everywhere instead of an FQDN or true inventory
hostname.

Joshua Boniface 5797535997 Adjust documentation and behaviour of cpuset
1. Detail the caveats and specific situations and ref the documentation
which will provide more details.

2. Always install the configs, but use /etc/default/ceph-osd-cpuset to
control if the script does anything or not (so, the "osd" cset set is
always active just not set in a special way.

Joshua Boniface 8ac2a5ea0c Adjust default ceph.conf parameters
1. Remove an explicit OSD journal size, especially such a small one (no
clue why I ever added that...)

2. Add max scrubs, disable scrub during recovery, and set scrub sleep.

3. Add max backfills, tune recovery sleep to 0 to prioritize recovery.

Joshua Boniface 732bfe732c Add Ceph OSD cpuset tuning options
Allows an administrator to set CPU pinning with the cpuset tool for Ceph
OSDs, in situations where CPU contention with VMs or other system tasks
may be negatively affecting OSD performance. This is optional, advanced
tuning and is disabled by default.
