This patch introduces support for Cephs RBD namespaces.
A new storage config parameter 'namespace' defines the namespace to be
used for the RBD storage.
The namespace must already exist in the Ceph cluster as it is not
automatically created.
The main intention is to use this for external Ceph clusters. With
namespaces, each PVE cluster can get its own namespace and will not
conflict with other PVE clusters.

v1 -> v2:
use `defined` to check if a namespace if configured instead of
evaluating the value which would wrongly evaluate to false if the pool
would be called '0'. Thx @Thomas for pointing this out.
much less changes since the 'centralize rbd path concatenation' patch
took care of most instances.
removed empty new lines that I did not catch in the previous version
rvc -> v1:
add --namespace parameter centrally in sub $build_cmd. All commands
except one (rbd unmap) support it. To handle commands that don't support
it, a hash with them was introduced.
In a few places paths (FS, Ceph hierarchy) are needed. These are the
places scattered throughout the plugin where the namespace is inserted
if it is configured.
