Presently, k6 tests report average response time for POST requests for creating CM-handles, as well as time for all CM-handles to be ready.

This task is to instead report the throughput, in CM-handles per second, so that it aligns with the characteristic requirements (see test case 1 in https://wiki.onap.org/display/DW/CPS-391Spike%3A+Define+and+Agree+NCMP+REST+Interface#CPS391Spike:DefineandAgreeNCMPRESTInterface-Characteristics-WIP)

• A single plot showing CM-handles registered per second (this includes the time be READY state)
