Mandychen/migrate buildkite to GitHub actions

[mandyschen]

What changed?
Added Github Actions implementation to buildkite pipeline pipeline-master.yml

Why?
To keep all the pipelines in the same place

How did you test it?
Ran the pipeline through my own commits. Plan to test on different commits and compare outcomes with prior buildkite pipeline

Potential risks
Some issues aren't caught because they weren't caught in the pipeline. Some good PRs cant be merged because they were falsely caught by the pipeline

Release notes

Documentation Changes

The CI failed. Looks like it might be an issue related to the Docker path.

@bowenxia After I reran it it seems like it fixed itself. I think it might have been a timing issue where Cassandra was not fully done initializing before the next command ran so it ran into a path not found error?

I never ran into any issues with tests failing in GitHub Actions except for in the unit test when running make cover_profile so thats the only command with an automatic retry. I'll add retries to the rest of the commands just to cover all the bases since that's what the buildkite version does.
