Move everything related to watching / updating the configuration to a separate pkg. That makes the code easier to follow, and allows us to properly unit test watching the configuration. Signed-off-by: Miguel Duarte Barroso <[email protected]>
This allows us to use cron expressions with seconds in the tests, thus allowing the test run to finish a lot quicker. Signed-off-by: Miguel Duarte Barroso <[email protected]>

@dougbtv I've added a unit test that shows this working. I think that's enough ... I'm OK with merging. Let's talk about it in 2024. |
