92ad2ceec9 rbd: read clusterID and PoolID from mapping
Whenever Ceph-CSI receives a CSI/Replication
request it will first decode the
volumeHandle and try to get the required
OMAP details if it is not able to
retrieve, receives a `Not Found` error
message and Ceph-CSI will check for the
clusterID mapping. If the old volumeID
`0001-00013-site1-storage-0000000000000001
-b0285c97-a0ce-11eb-8c66-0242ac110002`
contains the `site1-storage` as the clusterID,
now Ceph-CSI will look for the corresponding
clusterID `site2-storage` from the above configmap.
If the clusterID mapping is found now Ceph-CSI
will look for the poolID mapping ie mapping between
`1` and `2`. Example:- pool with name exists on
both the clusters with different ID's Replicapool
with ID `1` on site1 and Replicapool with ID `2`
on site2. After getting the required mapping Ceph-CSI
has the required information to get more details
from the rados OMAP. If we have multiple clusterID mapping
it will loop through all the mapping and checks the
corresponding pool to get the OMAP data. If the clusterID
mapping does not exist Ceph-CSI will return an `Not Found`
error message to the caller.

4859f2dfdb util: allow configuring VAULT_AUTH_MOUNT_PATH for Vault Tenant SA KMS
The VAULT_AUTH_MOUNT_PATH is a Vault configuration parameter that allows

f2d5c2e0df util: add vaultAuthNamespace option for Vault KMS
The new `vaultAuthNamespace` configuration parameter can be set to the
Vault Namespace where the authentication is setup in the service. Some
Hashicorp Vault deployments use sub-namespaces for their users/tenants,
with a 'root' namespace where the authentication is configured. This
requires passing of different Vault namespaces for different operations.

Example:
 - the Kubernetes Auth mechanism is configured for in the Vault
   Namespace called 'devops'
 - a user/tenant has a sub-namespace called 'devops/website' where the
   encryption passphrases can be placed in the key-value store

The configuration for this, then looks like:

    vaultAuthNamespace: devops
    vaultNamespace: devops/homepage

Note that Vault Namespaces are a feature of the Hashicorp Vault
Enterprise product, and not part of the Open Source version. This
prevents adding e2e tests that validate the Vault Namespace
configuration.

72d56cb8db e2e: use original namespace for retrying resize check
expandPVCSize() uses the namespace of the PVC that was checked. In case
the .Get() call fails, the PVC will not have its namespace set, and
subsequent tries will fail with errors like:

    Error getting pvc in namespace: '': etcdserver: request timed out
    waiting for PVC  (9 seconds elapsed)
    Error getting pvc in namespace: '': an empty namespace may not be set when a resource name is provided

By using the original namespace of the PVC stored in a separate variable
as is done with the name of the PVC, this problem should not occur
anymore.

16ec97d8f7 util: getCgroupPidsFile produces striped path when extra : present
This commit uses `string.SplitN` instead of `string.Split`.
The path for pids.max has extra `:` symbols in it due to which
getCgroupPidsFile() splits the string into 5 tokens instead of
3 leading to loss of part of the path.
As a result, the below error is reported:
`Failed to get the PID limit, can not reconfigure: open
/sys/fs/cgroup/pids/system.slice/containerd.service/
kubepods-besteffort-pod183b9d14_aed1_4b66_a696_da0c738bc012.slice/pids.max:
no such file or directory`
SplitN takes an argument n and splits the string
accordingly which helps us to get the desired
file path.

526ff95f10 rbd: add support to expand encrypted volume
Previously in ControllerExpandVolume() we had a check for encrypted
volumes and we use to fail for all expand requests on an encrypted
volume. Also for Block VolumeMode PVCs NodeExpandVolume used to be
ignored/skipped.

With these changes, we add support for the expansion of encrypted volumes.
Also for raw Block VolumeMode PVCs with Encryption we call NodeExpandVolume.

That said,
With LUKS1, cryptsetup utility doesn't prompt for a passphrase on resizing
the crypto mapper device. This is because LUKS1 devices don't use kernel
keyring for volume keys.

Whereas, LUKS2 devices use kernel keyring for volume key by default, i.e.
cryptsetup utility asks for a passphrase if it detects volume key was
previously passed to dm-crypt via kernel keyring service, we are overriding
the default by --disable-keyring option during cryptsetup open command.
So that at the time of crypto mapper device resize we will not be
prompted for any passphrase.
