A couple fixes for Quantum:
* The Load Balancers panel is now no longer enabled by
default since it is disabled by default in Quantum.
* Security Groups and Security Group Rules now support both
Nova's integer IDs and Quantum's UUID IDs.
* Regroups all the Quantum panels into a "Manage Network"
panel group to match "Manage Compute" above it.
* Adds tests for both int and UUID ids in the Security
Group test suite.
Fixes bug 1153477 and fixes bug 1155244.
