The discovery daemon is not needed in most scenarios, therefore we disable it by default. More and more clusters are moving to the cluster-on-pvc scenario which certainly does not need the local discovery. Even where clusters are not running on PVCs, the discovery is not needed since the device discovery is again performed in the osd prepare job. Signed-off-by: Travis Nielsen <tnielsen@redhat.com>

Breaking Changes
Ceph
- Ceph mons require an odd number for a healthy quorum. An even number of mons is now disallowed.
- Update deprecated CRD apiextensions.k8s.io/v1beta1 to v1 (#6424)
- preservePoolsOnDelete is deprecated for CephFilesystem and is no longer allowed because of data-loss concerns. preserveFilesystemOnDelete acts as a replacement and preserves the filesystem when the CephFilesystem CRD is deleted (which implicitly includes all associated pools). See #6495 for more details.
- The discovery daemon is disabled by default since the discovery is not necessary in most clusters. Enable the discovery daemon if devices are being added to nodes and you want to automatically configure OSDs on new devices without restarting the operator.
