Ceph-CSI support for fscrypt encryption of cephfs.
To achieve this commit add capability of mounting the
required `rook-ceph-csi-kms-config` configmap into
csi-cephfsplugin-provisioner and nodeplugin pods.
Further it modifies the ClusterRoles `cephfs-csi-nodeplugin` and
`cephfs-external-provisioner-runner` to grant privileges
required for reading encryption configuration and fetching
encryption secrets from either kubernetes secrets or
from a Key Management System (KMS).
These privileges are essential for the proper functioning of
ceph-csi-cephfs with fscrypt encryption.
The following privileges have been added:
- `secrets/get`: Allows reading of secrets for encryption.
- `configmaps/get`: Grants access to configuration maps,
this is used to read encryption configuration.
- `serviceaccounts/get`: Enables retrieval of service accounts for
authentication to KMS and for retrieving encryption secrets
stored there.
- `serviceaccounts/token/create`: Allows creation of service account tokens,
which are required for authenticating requests to KMS
when retrieving encryption secrets.
The commit also updated the csi documentation to include cephfs
in the encryption section, with examples updated accordingly.
