When CPU requests and limits are assigned to a pod,
the pod will be guaranteed the requests, up to the limits.
Even if there are spare CPU cycles, the pod cannot use
them. Thus, pods can be unnecessarily denied compute
when they need to burst if the limits are set.
Therefore, it is not recommended to set CPU limits
since the CPU requests are already guaranteeing that
no pod will be starved at least for its requests.

Allow end-user to have full control on NFS-Ganesha liveness probe:
- Disabled
- Enabled, using user-provided definition
- Enabled, using Rook's default liveness probe for Ganesha.

The sssd.conf may refer to additional files, like a CA bundle or TLS
certificates. These files need to be made available in the SSSD sidecar.
With the new `sssdGenericFiles` reference to a VolumeSource and a
`MountPath`, a provided `sssd.conf` can use the additional files.

Implement the SSSD sidecar design for NFS.
Because NFS documents are getting long, create an NFS
`Storage-Configuration` section with separated topics to keep the `NFS
Overview` document sane.
Adjust the SSSD design to allow any VolumeSource, not just ConfigMaps.

Create the ".nfs" config pool by default so that users aren't required
to create it via CephBlockPool.

The built-in pools device_health_metrics and .nfs created by ceph
need to be configured for replicas, failure domain, etc.
To support this, we allow the pool to be created as a CR.
Since K8s does not support underscores in the resource names
the operator must translate this special pool name into
the name expected by ceph.
This also sets the basis for allowing filesystem data
pools to specify the desired pool name instead of requiring
a generated name.

Remove the poolConfig in CephNFS to prevent different CephNFS CRs from
contending to change the replication spec of the default NFS pool.

NFS docs need to be updated to reflect changes between Octopus and
Pacific, how users are affected, how NFS is configured differently
between the Ceph versions, and how to upgrade from one Ceph version to
the other.
