Remove noisy scenarios and add new scenario

[Anilm3]

The current microbenchmark utility uses scenarios to test independent features, this suffers from unstable results due to many factors, such as code layout and alignment, WAF "runtime" changes, etc. This applies to all tests except the global ruleset one.
To simplify things and potentially resolve the constant noise from benchmarks, the current scenario based benchmark will only be used as a macrobenchmark which will contain only wide-ranging scenarios, starting with a single, full ruleset one.

Note that the benchmarks will fail as no scenarios are common to the master branch.
