This hunk is from aca45d7d08fd8c3f32849331eba4620e2726282a, a much
larger change in master that added type annotations all over the place.
It just brings src/pybind/mgr/cephadm fully in sync with master.

mgr/cephadm: tolerate failure to update daemon caps
If we're upgrading from 15.2.0, we may fail to update caps. Instead of
failing the upgrade hard, warn to the log and continue. This is less
than ideal, but the caps will get corrected the next time the daemon is
redeployed on the next upgrade, and most likely the previous caps will
continue to work (given they were presumably working before the upgrade).

mgr/cephadm: fix get_keyring_with_caps
1- Pass caps to 'auth get-or-create'
2- Only try 'auth caps' if the get-or-create failed
Note that the 'auth caps' step can fail if upgrading from 15.2.0 since
'profile mgr' didn't include 'auth caps' until 15.2.1. We're not
addressing that for now...

python-common: count-per-host must be combined with label or hosts or host_pattern
I think this is better for the same reason we made PlacementSpec() not
mean 'all hosts' by default. If you really want N daemons for every host

We already have to examine existing daemons to choose the placements.

mgr/cephadm/schedule: respect count-per-host
In the no-count cases, our job is simple: we have a set of hosts specified

do N instances for each of those hosts.

mgr/cephadm: do not worry about even # of monitors
Ceph works just fine with an even number of monitors.
Upside: more copies of critical cluster data
Downside: we can tolerate the same number of down mons as N-1, and now
we are slightly more likely to have a failing mon because we have 1 more
that might fail.
On balance it's not clear that have one fewer mon is any better, so avoid
the confusion and complexity of second-guessing ourselves.

Removed the injected_argv parameter and the injection of code in the cephadm
script we send to hosts.
Now the script is copied and after that we execute the cephadm command.

part of a future PR, together with other prs to:
- Introduce cephadm version
- Get rid of packaged/root mode
- Use pex or eggs

they don't exist.

This is just so we can load up a stored spec after upgrade. We'll silently
drop it, since we have the service_id, and this was only used to generate
that anyway.

mgr/orchestrator: drop $realm.$zone naming convention
- Let users name the rgw service(s) whatever they like
- Make the rgw_zone and rgw_realm arguments optional, so that they can
omit them and let radosgw start up in the generic single-cluster
configuration (whichk, notably, has no realm).
- Continue to set the rgw_realm and rgw_zone options for the daemon(s),
but only when those values are specified.
- Adjust the CLI accordingly. Drop the subcluster argument, which was
only used to generate a service_id.
- Adjust rook. This is actually a simplification and improved mapping onto
the rook CRD, *except* that for octopus we enforced the realm.zone
naming *and* realm==zone. I doubt a single user actually did this
so it is not be worth dealing with, but we need a special case for
where there is a . in the service name.

It is simpler to consider this out of scope for the orchestrator. The
