Milestone ProtoGENI: control plane integration of cluster-mates

Work with other groups and projects to work towards integration of the following into the evolving ProtoGENI testbed:

ProtoGENI programmable backbone nodes;
Programmable host clusters at Univ Utah;
VINI-specific features;
Residential wireless access network ("Homenet") at CMU;
Programmable host cluster at CMU;
Wireless propagation emulator at CMU;
Instrumentation and measurement tools from Kentucky

Completed: all cluster-mates have indicated they have sufficient integration support for their Spiral 1 commitments.
