- 512 -> 1024MB vm memory (had sporadic oom-failures with the lower setting)
- set "auth_allow_insecure_global_id_reclaim=false" as described here: https://docs.ceph.com/en/latest/security/CVE-2021-20288/

The library does not depend on stdenv, that `stdenv` exposes `lib` is
an artifact of the ancient origins of nixpkgs.

by default
- the pg_autoscaler will force new empty pools down to 32 pgs
- device monitoring metrics consumes 1 pool with 1 pg

bootstraping method

This prevents services to be started before they're initialized, and
renders the `systemd.targets.ceph.wantedBy = lib.mkForce [];` hack in
the vm tests obsolete - The config now starts up ceph after a reboot,
too.
Let's take advantage of that, crash all VMs, and boot them up again.

extraServiceConfig
Don't pass user and group to ceph, and rely on it to drop ceps, but let
systemd handle running it as the appropriate user.
This also inlines the extraServiceConfig into the makeService function,
as we have conditionals depending on daemonType there anyways.
Use StateDirectory to create directories in
/var/lib/ceph/${daemonType}/${clusterName}-${daemonId}.
There previously was a condition on daemonType being one of mds,mon,rgw
or mgr. We only instantiate makeServices with these types, and "osd" was
special.
In the osd case, test examples suggest it'd be in something like
/var/lib/ceph/osd/ceph-${cfg.osd0.name} - so it's not special at all,
but exactly like the pattern for the others.
During initialization, we also need these folders, before the unit is
started up. Move the mkdir -p commands in the vm tests to the line
immediately before they're required.

We seem to be relying on those being present during runtime anyways.

sharing of the admin keyring to the shared directory instead of netcat

Rename the old ceph test to ceph-single-node and add a new test
ceph-multi-node. The ceph-single-node represents a dev cluster whereas
ceph-multi-node is closer to a prod cluster.
