Description of problem:

if we want to delete a volume that has snapshots we need to manually delete the snapshots before deleting the volumes. 
I think that the user should be given a choice if they want to either remove the volume with all its snapshots or not. 

Version-Release number of selected component (if applicable):

openstack-cinder-2013.1.2-3.el6ost.noarch

How reproducible:

100%

Steps to Reproduce:
1. create a volume
2. create a snapshot from the volume
3. try to remove the volume

Actual results:

we will not be able to remove the volume and there is no force param to force remove volume + its snapshots

Expected results:

we should allow the user to remove the volume + its snapshots if they wish instead of having the user delete the snapshots manually.
