DEBUG-2657 DRY benchmarks

[p-datadog]

Extract repetitive configuration of benchmarks into a helper module, refactor benchmarks to use the new configuration DSL.

What does this PR do?

Extract repetitive configuration of benchmarks into a helper module, refactor benchmarks to use the new configuration DSL.

Motivation:

Benchmarks have a lot of duplicated code and they do not all consistently use the tooling available, like the dogstatsd reporter. This PR removes code duplication and unifies benchmarks' behavior.

Additional Notes:

Tracing benchmark not converted yet because I think it should be split into separate files to follow the profiling benchmark's pattern.

How to test the change?
