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.

Currently, we need to configure the Ceph external Admin keyi
in the Rook deployment to be able to connect to an external Ceph cluster.
If we wanted to run in a multi-tenant fashion
were several K8s/Rook clusters wanted to connect to the same external ceph cluster,
each K8s deployment would have the access to the External Ceph Admin key
and could potentially access or delete the Data
from pools that belong to other k8s/Rook Clusters.
Now the admin key is optional but the helper script create-external-cluster-resources.sh
will help create the necessary keys/users to connect to that cluster.

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.

The helpers for executing a process have long required an actionName
param which is not being used. Now we remove the old param
while also cleaning up various other usages of the exec
package.

The ceph commands are now only written to the log in debug mode.
For commands that change the system state we now ensure that
a useful log entry is written. If all the details of the ceph
commands are needed, debug logging should still be enabled.

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.

this adds a structure to hold various settings related to executing ceph
cli commands, and introduces a common interface for configuring and
running such commands.

The CephCluster resource will now expose the health of the ceph cluster
so admins can query the status with k8s api or kubectl instead of
needing to run the rook toolbox. The operator will query the
ceph status periodically and update the status in the custom resource.

The Ceph CLI has the flag option '--connect-timeout' which controls the
timeout of the command when reaching out to a monitor. If the connection
cannot be established within 15 seconds, the command will fail. The
default value in Ceph is relatively long (300sec IIRC). This is a
problem when monitors have trouble reaching out quorum, since this means
the command will only fail after 300 sec.
Now we fail faster.
