Ability to configure default quotas for new projects (#27)

* Ability to configure default quotas for new projects

As documented on the Juniper / Contrail wiki:
https://github.com/Juniper/contrail-controller/wiki/Defining-default-Quotas

* docs can be misleading, it really needed underscores. also added all lbaas  options now.

* Making params singular (and aligned with neutron internal naming).
