Automating the make release for task-processing - COMPINFRA-3567

[EmanElsaban]

automating the release process for this repo since its currently manual. We used to follow these steps before manually:

• merge change
• Make new version by changing version in init
• git checkout master
• git pull
• git tag v0.6.0
• git push origin master v0.6.0

then wait for jenkins to push the new release to pypi

Testing

1. Triggered the guards locally:

• tested modifying a tracked file (init.py) other than the makefile then running make release to see if it will fail with a warning and it did:

(py310) emanelsabban@dev208-uswest1adevc:~/pg/task_processing$ make release
Error: working directory is not clean; only changes to Makefile are allowed when cutting a release.
make: *** [Makefile:37: release] Error 1

• tested checking to another branch then running make release. It should fail and it did:

(py310) emanelsabban@dev208-uswest1adevc:~/pg/task_processing$ make release
Error: must be on master branch.
make: *** [Makefile:38: release] Error 1

• tested tag collision by attempting make release on the current tag and it failed with :

(py310) emanelsabban@dev208-uswest1adevc:~/pg/task_processing$ make release
Error: tag v1.3.5 already exists and points at e3a4d336c00280bab6be052db31026d65e9ee761
make: *** [Makefile:39: release] Error 1

2. Tested the full make target by commenting the push command and change the tag to v1.3.6 then verified that the commit and tag look right:
