osd/scrub: increasing max_osd_scrubs to 3
Bug reports seem to hint that the current default value of
'1' is too low: the cluster is susceptible to scrub scheduling
delays and issues stemming from local software/networking/hardware
problems, even if affecting a very small number of OSDs.
Squid will include a major overhaul of the way scrubs are counted
in the cluster, providing a better solution to the problem. For
now - modifying the default is an effective stop-gap measure.

cephadm: make custom_configs work for tcmu-runner container
This is intended to be a temporary workaround to make
custom config files be able to be mounted into
the tcmu-runner container. The hope is to refactor
cephadm's iscsi handling for squid, but a patch
like this could be useful for iscsi in older
releases where currently custom config files
are unusable for the tcmu-runner container
What this patch actually does is have us write the
custom config files to a dir for the tcmu-runner
container so that the rest of the logic works without
change. I thought this would be easier to remove later
than a patch that integrates more with the container
mounts or general deployment

cephadm: run tcmu-runner through script to do restart on failure
Currently, cephadm runs tcmu-runner as a background
process inside the unit file deployed for iscsi
(rbd-target-api is the primary process). This means
if tcmu-runner crashes for whatever reason, systemd
will not attempt to restart it. This commits sets
up a script to serve as the container entrypoint
for the tcmu-runner container that will run
tcmu-runner and also restart it on failure
(unless there are too many failures in a short
period, at which point it gives up).
The hope is to eventually drop use of this script
for a better solution in squid onward, but this
should be helpful on older releases (quincy and
pacific at least) where we won't be able to
bring that better solution

cephadm: add tcmu-runner to logrotate config
This process could be used to set up the tcmu-runner
to log to a file much like other ceph daemons
- create /etc/tcmu directory
- create /etc/tcmu/tcmu.conf directory with default options
- change dir to /var/log
- change log level to 4
- add -v /etc/tcmu:/etc/tcmu to tcmu-runner container podman line in unit.run
In order to support this (mostly for debugging) we should
add tcmu-runner to the logrotate config

qa/cephadm: add test for ca signed keys
Test that bootstraps with a CA signed key using
the use_ca_signed_key cephadm override. Then follows
up by doing a check-host on each host which verifies
the cephadm mgr module can reach and authenticate with
the nodes using the new key setup.
This probably should really be a workunit, but
I didn't want to create a full new section for
this test and I needed a section that didn't
already run the cephadm task for every test. I could
see this being moved into some sort of

call that does the same
Error EINVAL: ServiceSpec: 'dict' object has no attribute 'validate'

spec assuming all osd specific fields are either defined
in the 'spec' section or outside of it, but not mixed in.
We could also just consider these specs to be invalid

to make the minor adjustment for it to work, given there doesn't
seem to be an issue with mixing the styles for specs for
