Implement More Custom Constraints for Neutron

https://blueprints.launchpad.net/heat/+spec/neutron-custom-constraint

Now only network constraint is supported for neutron, we need more constraints like subnet, port, router etc.

Problem description

Many resources have some properties related with network, now neutron custom constraints only support network constraint, haven’t support subnet/port/router constraints.

Proposed change

Add 3 custom constraints to neutron.

  1. ‘neutron.subnet’ for subnet constraint.
  2. ‘neutron.port’ for port constraint.
  3. ‘neutron.router’ for router constraint.

Alternatives

None
