[Enhancement]: Simplify `Adding New Health Check`

[luccabb]

Adding New Health Check page has 9 steps to add a new health check into the codebase.

This github issue is not asking explicitly for a given enhancement, but for simplification of the process where possible. I'll list some ideas below, simplification shouldn't be limited to those ideas:

1. a new def check_example function requires 75 lines, mostly boilerplate. we should aim to reduce this.

2. too many manual actions are required from the user, can we create a script that handles many of the boilerplate steps:

$ bin/create_new_health_check.sh <check-name>
# creates the check file, implements click interface, registers the check, add killswitches, ...
# shows a pointer of instructions to the user for the remaining steps that we can't possibly automate with the above

Sounds interesting. What are the CI checks that might need to be added if this were to be implemented? What parts of the health-check creation process currently cause the most friction for maintainers?

Could I take up this feature request?

[luccabb]

@theap06 yes! for ci tests, maybe ensure some basic functionalities with something like scrut

if you wanna discuss your approach more feel free to join the discord!

Already joined! Should I draft up a design doc?

@theap06 probably makes sense. open it as a new issue and add the rfc tag.

if you have small improvements, feel free to open these straight as PRs
