This PR modifies the execCryptSetupCommand so that
the process is killed in an event of lock timeout.
Useful in cases where the volume lock is released but
the command is still running.

This commit adds the support for storing the CephFS omap data
in a namespace specified in the ceph-csi-config ConfigMap under
cephFS.radosNamespace field.
If the radosNamespace is not set, the default radosNamespace will
be used i.e, csi.

This commit adds `GetCephFSRadosNamespace` util method that returns

If not specified, the method returns the default RadosNamespace
i.e, csi.

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

Prevent re-use of a destroyed connection by setting it to `nil`. This
way it is also safe to call `Destroy()` multiple times without causing a
panic.

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

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

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.

For core K8s API objects like Pods, Nodes, etc., we
can use protobuf encoding which reduces CPU consumption
related to (de)serialization, reduces overall latency
of the API call, reduces memory footprint, reduces the
amount of work performed by the GC and results in quicker
propagation of objects to event handlers of shared informers.

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.

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.

While dealing with CephFS fencing we evict the
clients and block the IPs from the CIDR range
that do not have any active clients individually.
While Unfencing, the IP is removed via the
CIDR range which fails to remove the individual
IPs from Ceph's blacklist.
This PR fetches the blocklist from ceph and
removes the IPs in blocklist that lie inside
the CIDR range along with their unique nonces.
