Introduce end-to-end performance test bed

[tigrannajaryan]

The goal is to a create a test best - controlled environment and tools for conducting performance tests for the OpenTelemetry Agent, including reproducible short-term benchmarks, long-running stability tests and maximum load stress tests.

The test bed must allow specifying a configuration of the test, the load that needs to be generated, and be able to run and produce machine and human readable results. It should be possible to run the test bed locally on a developer machine or on a cloud.

Here is a more detailed proposal:

@flands can you assign this to me?

Thanks, @SergeyKanzhelev

@bogdandrutu @SergeyKanzhelev I have the first version of the performance test bed implemented and running. The repo is here https://github.com/Omnition/opentelemetry-service-testbed and the execution results look like this https://github.com/Omnition/opentelemetry-service-testbed/blob/master/tests/results/TESTRESULTS.md

We would like to contribute this to OpenTelemetry. The only question is if it possible for me and one more developer from Omnition to be assigned as Maintainers on this particular repo. We plan to continue to actively improve the test bed and want to make sure we will not be blocked during the active development phase (which can happen if someone else outside the company needs to approve the PRs). Do you think it is possible to do?

[SergeyKanzhelev]

@tigrannajaryan repos looks to be private. If those are generic enoguh - we should definitely pick those up.

I assume you want a separate repository, not this one. Every repo is bootstrapped with a couple of maintainers. Ideally from different companies. So the standard process of becoming approver and maintainer can work. As we are in early stages we are expediting this process. So it is absolutely possible to make a repo and assign maintainers quickly. However, I'd suggest to get support from anybody from other company to have a "healthy" repository.

@SergeyKanzhelev Sorry, I have just made it public if you want to have a look.
Let me see if there is anyone else from other companies interested in being an additional maintainer.

@bogdandrutu @@songy23 any of you interested?

[songy23]

Feel free to add me, or we can just reuse the code owners in this repo.

[tigrannajaryan]

Thanks @songy23 :-)

@SergeyKanzhelev would it be enough to bootstrap the testbed with me, @pjanotti (also from Omnition) and @songy23 as maintainers?

[SergeyKanzhelev]

Absolutely. I see no problems with this. I can set everything up later tonight or in the morning tomorrow.

[tigrannajaryan]

Thanks @SergeyKanzhelev

Let me know if there is anything that I can help with. You can either fork our repo and I will delete our copy or I can transfer ownership of our repo to open-telemetry Github org. Whichever you prefer.

[SergeyKanzhelev]

You can send PR here: https://github.com/open-telemetry/opentelemetry-service-testbed

I will make you maintainers once PR will be approved in community repo. Just in case anybody have concerns

[tigrannajaryan]

@SergeyKanzhelev here is the PR: https://github.com/open-telemetry/opentelemetry-service-testbed/pull/2
Thank you.
