22a86c568e rbd: default nouuid if the formattype is xfs
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.

45d1404d3e rbd: split buildCreateVolumeResponse() from CreateVolume()
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.

c89c68e9ea rbd: use 'rv' as name of the rbdVolume (golint)
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.

805f10fd71 rbd: remove unused rbdVolume.open()
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.

01edaf8a71 move rbdVolume connection details to utils.ClusterConnection
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.

0991cdf498 make CephFS SubvolumeGroup configurable
The name of the CephFS SubvolumeGroup for the CSI volumes was hardcoded to "csi". To make permission management in multi tenancy environments easier, this commit makes it possible to configure the CSI SubvolumeGroup.

c8271fe64c journal: move voljournal.go to a new package
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.

32839948ef cleanup: move pkg/ to internal/
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.

Closes: #903
