adding quota for number of block volumes allowed being attached to an instance

Registered by Puneet on 2015-06-12

This blueprint has been superseded. See the newer blueprint "nova improvement of maximum attach volumes more than 26 vols" for updated plans.

Currently openstack does not support limiting the total number of block volumes that can be attached to an instance. It can be a useful quota which, on after implementation, will restrict the deterioration of VM performance disallowing a unlimited number of block volumes attachments to a VM.
