chore(ci): compute operations throughput on benchmarks results

In addition to values currently parsed and sent to database, now
throughput is also computed. This computation is done only on
mean values. New results are:
 - operations per ms
 - operations per dollar spent which depends on the machine used
   to perform the benchmarks
