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.

This commit adds `GetCephFSRadosNamespace` util method that returns

If not specified, the method returns the default RadosNamespace

The rbdSnapshot/rbdImage object implements all functions for a useful
Snapshot interface. The rbd.Manager will be able to use this for

The go-ceph rbd package provides the GroupSnapGetInfo function, but it
may return ErrUnsupported when called. Returning this error after
advertising the support for VolumeGroupSnapshot seems ugly.
In order to advertise support for VolumeGroupSnapshot,
SupportsGroupSnapGetInfo() can be used, which detects the required C
function of librbd.

`ensureImageCleanup()` can cause a panic when an image was deleted, but
the journal still contained a reference. By opening the IOContext before
using, an error may be returned instead of a panic when using a `nil` or
freed IOContext.

The go-ceph rbd.GroupCreate() now returns ErrExist in case the group
that is created, already exists. The previous check only ever matched
the string comparison, which is prone to errors in case the contents is
modified by go-ceph.

The `repairImageID()` function is useful for the `rbdSnapshot` objects
as well. Move it to the `rbdImage` struct that is the base for both

There is no need for the `Manager.DeleteVolumeGroup()` function as
`VolumeGroup.Delete()` should cover everything too.
By moving the `.Delete()` functionality of removing the group from the
journal to the shared `commonVolumeGroup` type, a volume group snaphot
can use it as well.

When an `.Destroy()` is called on an rbdImage (or rbdVolume or
rbdSnapshot), the IOContext, Connection and other attributes are
invalid. When using a destroyed resource that points to an object that
was allocated through librbd, the process most likely ends with a panic.

When an `rbdVolume` or `rbdSnapshot` is not connected with credentials
to the Ceph cluster, operations may try to get the IOContext which then

A function called `setImageOptions()` is expected to set the passed
options on the volume. However, the passed options parameter is only
filled with the options that should get set on the RBD-image at the time
of creation.
The naming of the function, and it's parameter is confusing. Rename the
function to `constructImageOptions()` and return the ImageOptions to
make it easier to understand.
