NFR gating for Cerberus

[dsvellal]

NFRs have to be defined for Cerberus, and gated with every commit.

SimaoS, Aravind.H.U (@aravind666) - can you please add to NFRs that we'd want to automatically gate?

Sample NFR:

• Relative & absolute thresholds of execution time for all functionality provided by Cerberus
