rbd: move radosNamespace to RBD section

Browse Source 
As radosNamespace is more specific to
RBD not the general ceph configuration. Now
we introduced a new RBD section for RBD specific
options, Moving the radosNamespace to RBD section
and keeping the radosNamespace still under the
global ceph level configration for backward
compatibility.
