[FEATURE] Add support for microbenchmarks

[martin-gaievski]

Is your feature request related to a problem?

Repo does nor have internal instrumentation for writing and running microbenchmarks for low-level code, e.g. single method execution.

What solution would you like?

Frameworks like JMH can be enabled easy and does not required extra time for evaluation and security validation as they are already part of some other repos in OpenSearch.

What alternatives have you considered?

Profiling is possible for some type of tasks, but it's limited and harder to setup.

unfortunately JMH does not work for us due to restrictive license, it uses GPL. I see other repos had to roll it back even after enabling it first, e.g. opensearch-project/k-NN#2337
