b085577a4f rbd: add skipForceFlatten flag
added skipForceFlatten flag to skip
the image deptha and skip image flattening.
This will be very useful if the kernel is
not listed in cephcsi which supports deep
flatten fauture.

649aeb7aaf rbd: Add support for rbd ROX PVC mounting
if the PVC access mode is ReadOnlyMany
or single node readonly, mounting the rbd
device path to the staging path as readonly
to avoid the write operation.

If the PVC acccess mode is readonly, mapping
rbd images as readonly.

2f7e51076b rbd: unmap rbd image if the mounting fails
There is a bug in current code where the devicePath
is always empty and the rbd image unmap never
happens if nodeplugin fails to mount the rbd image
to the stagingpath.
This is a fix to unmap the rbd image if some issue
occurs after rbd image is mapped.

9fe7d1612e journal: In mount failure case, suggest to check the kernel logs
When mounting fails, the node-plugin should give a suggestion to check the
kernel logs so that users can report problems better.
Edited the existing log to include the message in both rbd and cephfs.
Fixes: https://github.com/ceph/ceph-csi/issues/1006

52603d595a journal: split journal types creating a new Connection type
Before, the one CSIJournal type was handling both configuration and
providing methods to make changes to the journal. This created the
temptation to modify the state of the global configuration object to
enact changes through the method calls.

This change creates a new type `journal.Connection` that takes the
monitors and credentials to create a short(er)-lived object to actually
read and make changes on the journal. This also avoid mixing the
arguments needed to connect to the cluster with the arguments needed
for the various journal read & update calls.

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.

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
