Add github actions for unit tests

[hayarobi]

• Any push of any branches will trigger short unit tests.
• User can trigger normal unit tests on demand.
• Also some long running unit tests will be skipped in short unit tests

When this PR was created, it run 2 different checks. This is not needed. It should run only the main one, made for PRs

Another option to avoid the duplicate run of actions is to unify the 2 actions into a single one.

First by removing the filter of branches on push on build_and_test.yaml

Then run the steps conditionally:

    - name: Complete Unit Test
      if: github.ref == 'refs/heads/master' || github.ref == 'refs/heads/develop'
      run: ...

    - name: Short Unit Test
      if: github.ref != 'refs/heads/master' && github.ref != 'refs/heads/develop'
      run: ...

But I suspect that it will still run the action again when the PR is merged...

If this is the case, then this would be better

I made a test on another fork and it did not work

You can see the PR here it run the short unit tests instead of the complete tests on the pull request

If you will no more use the branch, then it can be deleted
