Run static memory benchmarks from 'derailed_benchmarks' in CI

What does this MR do?

Two static memory benchmarks will be included in our CI pipeline.
It will load gems from the Gemfile and check the amount of RAM consumed as well as the number of objects allocated and retained.
Aggregated values will be included as 'metrics' into MRs while full reports will be downloadable as job artifacts.
