Study and propose software/hardware required to be installed in rackspace

This is a requirement from M2 milestone. Here is the exact text.

-----------------------------------------------------------

• Projects must specify (in the release plan) whether they are going to use OpenDaylight CI infrastructure for system test. It is recommended to use the OpenDaylight CI infrastructure unless there is some resource that is not available there, e.g., particular hardware or software.

• Start Test tools installation in rackspace. Projects that need any extra configuration or resources for test in the OpenDaylight CI infrastructure must have opened helpdesk tickets to add the configuration or resources.
  -----------------------------------------------------------

Even though we have passed M2 milestone, this still needs to be figured out and a decision made.
