Replace deprecated bincover with golang built-in coverage profiling tool

[luolanzone]

Describe what you are trying to solve @antoninbas reported that https://github.com/confluentinc/bincover is deprecated:

the bincover (https://github.com/confluentinc/bincover) project that we have been using for a couple of years to collect code 
coverage information when running unit tests has been deprecated. This is because starting with Go 1.20 (we still use Go 1.19 in 
Antrea, and we are waiting for Go 1.21, as we usually skip a version) there is a native way of doing the same thing: https://go.dev/testing/coverage/

Describe the solution you have in mind We should use built-in Go coverage profiling tool https://go.dev/testing/coverage/ to replace the deprecated one once golang 1.21 is released and Antrea is upgraded to it.

@luolanzone @ceclinux now that we are officially using Go v1.21, we can make progress on this issue. It will be good to take care of this, remove the bincover dependency, and hopefully simplify code coverage measurement for e2e tests.

Sure.

@luolanzone @ceclinux can we move forward with this issue in order to reduce tech debt?

I will take time to work on this, and it is expected to be finished in Antrea 1.16. Thanks.

@luolanzone Can I give this a try? I have some experience with testing and code coverage collection.

We have submitted this issue as a project idea for the LFX mentorship program: https://github.com/cncf/mentoring/pull/1129. So no-one should ideally work on this issue until we know if the proposal is accepted and if we can match a mentee to work on it. See https://docs.linuxfoundation.org/lfx/mentorship for more information on the program.

Okay, thanks for the heads up.

Hello! I'm considering applying to LFX for this project - looking forward to contribute! I'll poke around the good first issues so that I can get a better understanding of the code base before I apply to this project. Thanks!

Hi! I am considering applying to LFX mentorship for this project. I have some experience with code coverage and testing. I would love to explore more about Antrea and its vision and goals. Thanks!

[antoninbas]

For all the folks who have applied or are considering applying to one of the Antrea projects for the LFX mentorship program, we have published instructions to complete test tasks: https://github.com/antrea-io/antrea/discussions/5976. We will review your submissions for these tasks alongside other material (resume, cover letter) when selecting mentees. The deadline for submitting is February 20th 5PM PST.

@shikharish will work on this as part of the LFX mentorship program
