The function SetCSIDirectorySuffix was used only one per (long-lived,
gloabl) journal object. It is simpler to construct the journal objects
with this needed parameter:
1. As it is required to function and non-optional AFAICT
2. Removes the temptation to mutate global object
3. Reduces LOC with exact same functionality
4. SetCSIDirectorySuffix would not behave correctly if called a 2nd time
anyway.
Point 4. means that if you called the function twice to change the
suffix when you previously had "csi.volumes.alice", you'd get
"csi.volumes.alice.bob" instead of "csi.volumes.bob" what one would
expect.

The problem happens when multiple PVCs with the
same UUID are attached/mounted on a node. This
can happen after creating a PVC from a snapshot,
or cloning a PVC.
make nouuid as the default mount option if
the format type is xfs to avoid mounting
issues.

The gocyclo linter complains about the high complexity of the
CreateVolume() function:
> pkg/rbd/controllerserver.go:133:1: cyclomatic complexity 21 of func `(*ControllerServer).CreateVolume` is high (> 20) (gocyclo)
By splitting it up and separeting the creation of an exisint CSI Volume
object in buildCreateVolumeResponse(), the gocyclic linter does not
complain any longer.

golint has a pretty struct stylechek, it down not allow different
variable names for methods on an object:
pkg/rbd/rbd_util.go:970:1: receiver name rbdVol should be consistent with previous receiver name rv for rbdVolume (golint)
func (rbdVol *rbdVolume) ensureEncryptionMetadataSet(ctx context.Context) error {
^
pkg/rbd/rbd_journal.go:166:26: ST1016: methods on the same type should have the same receiver name (seen 2x "rbdVol", 3x "rv") (stylecheck)
func (rbdVol *rbdVolume) Exists(ctx context.Context) (bool, error) {
^
Rename the 'rbdVol' variable to 'rv' to make it consistent.

rbdVolume.open() was split from commit 5dd34732e1e while moving part of
the functionality to util.ClusterConnection. It seems that .open() is
not used anywhere at the moment, so drop it until follow-up patches
require it again.

The shared util.ClusterConnection can be used for rbd.rbdVolume and
cephfs.volumeOptions to connect to the Ceph cluster. This will then use
the shared ConnPool, and functions for obtaining connection details will
be the same across cephfs and rbd packages.
The ClusterConnection.Creds credentials are temporarily available until
all the functions have been adapted to use go-ceph and the connection
from the ConnPool.

This new journal package isolates journal logic from the rest of util
and helps draw bright lines between what is a generic utility function
and what is csi journal logic.
Done partly as preparation for making use of go-ceph in journal.
No functional changes are made except to update references to allow the
code to compile.

The internal/ directory in Go has a special meaning, and indicates that
those packages are not meant for external consumption. Ceph-CSI does
provide public APIs for other projects to consume. There is no plan to
keep the API of the internally used packages stable.
