Performance Benchmark Rest Apis

[rishabh6788]

Description

This PR introduces following rest apis to help opensource opensearch-project contributors submit ad-hoc benchmark runs on our jenkins infra. They do not need to log-in to the jenkins to submit the job as long as they are authorized using github teams.

• submitBenchmarkRun: Rest api to submit ad-hoc benchmark using artifact tarball. Will re-use jenkin's benchmark-pull-request job to run benchmark.
• submitBenchmarkEndpointRun: Rest api to submit ad-hoc benchmark against user's cluster endpoint. Will use benchmark-test-endpoint to run benchmark.

Generally good on the 1st pass.

In offline conversation, I raise the question of having a limit set in API Gateway so that to prevent potential spamming on the API calls.

Thanks.

Added throttling rule to api.
