This implements the "Ceph Config via Ceph Cluster CRD" design document
as a `cephConfig:` structure on the CRD.
This also fixes the `yq` commands used to manipulate the
`cluster-test.yaml` that caused CI issues for this PR and potentially
unknowingly others.

The /tmp dir is not always available in some environments.
The only directories the operator should rely on
are the directories that are in its pod spec.
For assimilate-conf now we use the /var/lib/rook
directory to generate files since we know it is
a valid emptydir mounted into the operator pod.

Change how Rook detects network CIDRs for Multus networks. The IPAM
configuration is only defined as an arbitrary string JSON blob with a
"type" field and nothing more. Rook's detection of CIDRs for whereabouts
had already grown out of date since the initial implementation.
Additionally, Rook did not support DHCP IPAM, which is a reasonable
choice for users. And more, Rook did not support CNI plugin chaining,
which further complicates NADs. Based on the CNI spec, network chaning
can result in any changes to network CIDRs from the first-given plugin.
All these problems make it more and more difficult for Rook to support
Multus by inspecting the NAD itself to predict network CIDRs. Instead,
it is better for Rook to treat the CNI process as a black box. To
preserve legacy functionality of auto-detecting networks and to make
that as robust as possible, change to a canary-style architecture like
that used for Ceph mons, from which Rook will detect the network CIDRs
if possible.
Also allow users to specify overrides for CIDR ranges. This allows Rook
to still support esoteric and unexpected NAD or network configurations
where a CIDR range is not detectable or where the range detected would
be incomplete. Because it may be impossible for Rook to understand the
network CIDRs wholistically while residing only on a portion of the
network, this feature should have been present from Multus's inception.
Improving CIDR auto-detection and allowing users to specify overrides
for auto-detected CIDRs rounds out Rook's Multus support for CephCluster
(core/RADOS) installations. No further architectural changes should be
needed for CephClusters as regards application of public/cluster network
CIDRs for Multus networks.

if the configuration is already set in the ceph
database, using `ceph config assimilate-conf`
will add the key and value if its missing but
it wont update the value if the key is already
present, To fix this problem we can remove the
key and add all the configurations once again.

that was applying them individually. Now we use the assimilate

Ceph upstream telemetry (which Rook users could optionally enable via
Ceph CLI or Dashboard) does not easily identify if a cluster is managed
by Rook. Identifying Rook clusters is possible only if users also enable
the rook mgr module, which is optional and not often used.
To get better upstream insights into Ceph clusters managed by Rook, set
a new 'rook-version' field in Ceph's generic k/v store. This field can
be used to determine if a cluster is managed by Rook by its presence.
It additionally provides information about the Rook version used to
manage the cluster, which is another piece of potentially useful
information.
Regarding Ceph cluster identification via telemetry:
Ceph telemetry is anonymous and uses a different ID from the Ceph
cluster ID. Identifying the Rook version in telemetry does not add
directly identifying information. Therefore, there should be little
risk that adding the Rook version field will decrease anonymity of Ceph
clusters via telemetry.

The mon config had two different implementations that have evolved
over the lifetime of the project. This is a simple refactor to remove
the SetConfig() option and stick with the MonStore as a single
implementation for updating the mon store.

We don't need to set log_file to empty string since "log_to_file" is set
to False. This is probably an old leftover/hack we were doing in the
past when "log_to_file" and other related options were not there.
Because of this line
https://github.com/ceph/ceph/blob/master/src/perfglue/heap_profiler.cc#L99,
Ceph looks for the log_file conf option. In our case it was empty, so
the logging would default to the current directory which points to the
container runtime root when not set and we don't have permission to
write there.
We now force it to Ceph's default so that existing cluster will get the
fix after upgrading.
Just removing the option allows us to get dump in /var/log/ceph.
Phew, what a bug!

To provide more context for executing commands in a ceph cluster,
the full clusterInfo is now passed to the ceph execution commands.
All information about the cluster will now be available throughout
all the areas of the operator. The namespace, ceph credentials,
mon endpoints, and other info is a core part of that cluster info.
Arguments passed through the controllers are also simplified for
mons, mgr, osds, and other daemons where the parameters had
become too complex.

The PG count on metadata pools should default to rgw_rados_pool_pg_num_min
instead of the more general default pg count. This means rgw pools
will default to 8 PGs instead of 32 PGs, which means a lot more pools
can be created before hitting the default PG limit.

When using the "errors" package, using `%+v` (extended format),
each Frame of the error's StackTrace will be printed in detail.
Let's only print `%v` to print the error.
If the error has a Cause it will be printed recursively.
Basically `%+v` has been replaced with `%v` for all `error` type
interfaces, whether the logger is Info, Warning or Error.

After further consideration and working with the feature for a few
weeks, the `configOverride` functionality seems to be more complexity
than is worth it for the expected benefit. Users still have the most
preferred option of setting configs in Ceph's config database using
`ceph cofig set` or the dashboard, and the override ConfigMap still
exists for fallback scenarios. The config database can still be used
by Rook for setting necessary configs, but the user has no way of
telling Rook to do so.

Allow users to specify overrides in the CephCluster CRD. The override
ConfigMap still exists for emergency situations and is mounted into
daemon pods directly instead of being merged into a Rook-created config
file.
Rook Ceph no longer uses a config file for managing daemons with the
exception of the OSDs which still generate a config in an init
container.
