Move Flank release job from Bitrise to GitHub Actions

[bootstraponline]

Author the user story for this feature

As a developer on Flank, I want to move the release job to GitHub actions so I can automatically release new versions of Flank.

---

The Flank release job on Bitrise sometimes flakes out. Let's move all the bitrise jobs to GitHub actions. As part of migrating the release job, we should probably build a Kotlin CLI that automates the release. Then the GitHub Action will simply invoke this Kotlin CLI that has the complex release logic.

Example error:

+ jfrog bt mcs flank/maven/flank/v20.07.0
[Info] Requesting content sync...
[Error] bintray response: 404 Not Found
{
  "message": "Version 'v20.07.0' was not found"
}

Any part of the release process can fail. Maven sync is particularly flaky. The Kotlin wrapper code should be smart enough to intelligently retry on error after a delay.

Here's the bitrise job yaml:

Steps to do in this PR

1. Create Empty template for each step on github action
2. Install GitHub hub not needed cause it is build in macOS machine
3. Check hub version not needed, see step 2, version 2.14.2
4. Get and set tag as environment variable
5. Update bugsnag
6. Delete old snapshot
7. [Gradle] Build flank (just invoke it using github actions)
8. [Gradle] Upload to bintray(just invoke it using github actions)
9. Rename flank jar
10. Hub remove old release
11. Remove old tag
    12a. if snapshot version release snapshot
    12b. if not snapshot version release stable
12. Sync bintray to maven central
13. Create documentation
