c9ad904331 cephfs: Add support for multiple subvolumegroups
With the current code base, the subvolumegroup will
be created once, and even for a different cluster,
subvolumegroup creation is not allowed again.

Added support multiple subvolumegroups creation by
validating one subvolumegroup creation per cluster.

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.

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.

f091374ba9 journal: remove SetNamespace setter function
The SetNamespace setter function was called only once, immediately after
the creation of a volume journal object in cephfs only.
Remove this function so that it is no longer implied that this field can
be mutated after the journal is created. In it's place, use an extended
"constructor" NewCSIVolumeJournalWithNamespace that takes a namespace
value at create-time only.

78a6de2bd0 journal: remove SetCSIDirectorySuffix to simplify journal creation
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.

0991cdf498 make CephFS SubvolumeGroup configurable

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.
