[MatheusFranco99]

Overview

Benchmark tests to:

• measure performance
• keep track of performance impact for each new protocol change

It includes performance tests for:

• Full duty
• Consensus full round
• Partial Signature messages
• QBFT message type by round and occurrence number

Example of output:

@GalRogozinski
I think this PR is super useful for us to have a view about our protocol and how our changes are improving it
Not only that, I find it super useful to have these views for later optimizations.
But, since I created this with not much care (just as some util for me), I would prefer putting it into a better shape before merging it, and even adding more analytics
