`reserveSnap()` can potentially fail halfway through, in that case it
needs to undo the snapshot reservation and restore modified attributes
of the snapshot.

Without the SnapshotGroupID in the Snapshot object, Kubernetes CSI does
not know that the Snapshot belongs to a group. In that case, it allows
the deletion of the Snapshot, which should be denied.

When creating a Snapshot with the new NewSnapshotByID() function, the
name of the RBD-image that is created is the same as the name of the
Snapshot. The `RbdImageName` points to the name of parent image, which
causes deleting the Snapshot to delete the parent image instead.
Correcting the `RbdImageName` and setting it to the `RbdSnapName` makes
sure that upon deletion, the Snapshot RBD-image is removed, and not the
parent image.

The Group Controller Server may need to fetch a VolumeGroupSnapshot that
was statically provisioned. In that case, only the name of the
VolumeGroupSnapshot is known and should be resolved to an object.

The GetVolumeGroupSnapshotByID function makes it possible to get a
VolumeGroupSnapshot object from the Manager by passing a request-id.
This makes it simple for the Group Controller Server to check if a
VolumeGroupSnapshot already exists, so it is not needed to try and
re-create an existing one.

A (CSI) VolumeGroupSnapshot object contains references to Snapshot IDs
(or CSI Snapshot handles). In order to work with a VolumeGroupSnapshot

When the rbd.Manager creates a VolumeGroupSnapshot, each RBD-snapshot
that is created as part of the RBD-group needs to be cloned into its own
RBD-image that will be used as a CSI Snapshot.
The VolumeGroup.CreateSnapshots() creates the RBD-group snapshot and
returns a list of the Snapshot structs.

The NewSnapshotByID() function makes it possible to clone a new Snapshot
from an existing RBD-image and the ID of an RBD-snapshot on that image.
This will be used by the VolumeGroupSnapshot feature, where the ID of an
RBD-snapshot is obtained for the RBD-snapshot on the RBD-images.

Each object is responsible for maintaining a connection to the journal.
By sharing a single journal, cleanup of objects becomes more complex as
the journal is used in deferred functions and only the last should
destroy the journal connection resources.

Commit 95733b3a9 introduced the `StoreGroupID()` function, but that
unfortunately set an empty key in the journal.
Passing the `csiGroupIDKey` key (with value `csi.groupid`) caused
setting `csi.csi.groupid` as a key. Reading the value back with the
right `csi.groupid` key always returned an empty value.

When the image is not closed, it keeps a watch open. This prevents the
CSI Controller to delete the Volume, as there is still a user of it.
