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.

RBD image metadata keys that start with '.rbd' are expected to be
internal to RBD itself and are not mirrored to remote sites. Renaming
the keys (dropping the '.' prefix) and using the new MigrateMetadata()
function now makes the keys available on remote sites too.
Closes: #2219
Signed-off-by: Niels de Vos <ndevos@redhat.com>
The new MigrateMetadata() function can be used to get the metadata of an
image with a deprecated and new key. Renaming metadata keys can be done
easily this way.
A default value will be set in the image metadata when it is missing
completely. But if the deprecated key was set, the data is stored under
the new key and the deprecated key is removed.

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.

It seems that the version of the key/value engine can not always be
detected for Hashicorp Vault. In certain cases, it is required to
configure the `VAULT_BACKEND` (or `vaultBackend`) option so that a
successful connection to the service can be made.
The `kv-v2` is the current default for development deployments of
Hashicorp Vault (what we use for automated testing). Production
deployments default to version 1 for now.
