GBP create group API does not allow specification of DNS nameservers

[ransari]

 Neutron's create subnet API
http://developer.openstack.org/api-ref-networking-v2.html#createSubnet

supports specification of subnet details such as :
-DNS Name servers
- Host Routes

Openstack Horzion's Create Networks /Subnet Details tab allows user to sepcify these subnet details

However, GBP create group API does not allow user to specify the above.
This option is not supported from GBP UI or CLI as well.
The minimum requirement for create group should be to enable specification of the DNS nameservers by reading this from a config file.

This will be addressed initially by providing an optional configuration in the following section:

[resource_mapping]
dns_nameservers = <list of name server ip addresses>

The configuration will have global scope and every subnet that is implicitly created for a PTG will be configured with this list.
