926f1e813c rbd: keep rados.IOContext for re-use
This prevents the need to open the IOContext for additional operations
on the image.

It also addresses a leak of the IOContext in case `rbdVolume.open()` was
called. The method only returned the `rbd.Image` without the possibility
to close the related IOContext.

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.

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.

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.
