consolidated benchmarks execution into python app

[dkijania]

Another required step for implementing benchmarks into mina codebase. This PR is implementation for step unify all benchmarks in code in https://github.com/MinaProtocol/mina/issues/16003.

Currently benchmarks are too diverse in form of output format. As a result I implemented wrapper python script which provides unified interfaces when dealing with mina benchmarks. see Readme.md for more information
