Security Group rule validation for ICMP rules

Currently there is no validation in Security Group rules
when an ICMP rule is added with icmp code alone. A rule
is getting added but there is a mismatch between SG rules
and the corresponding iptables rule that is added.
This patch does the necessary validation on the input.

Improved quota error message

Removed two negatives and showed a clear message when
tried to see quota of different tenants.
When a user who does not belong to a project tries to access the
quota of that project, the message that gets displayed is not clear.
In this change the user would understand the error more properly.

Nuage Plugin: Delete router requires precommit checks

There exist a case where deleting router from neutron without
deleting router-interface deletes router from VSD but not from neutron.
If router has an interface with subnet router deletion is not allowed.
Needs to precheck this condition before deleting router from
backend (VSD).
