Throttle connectivity check on connectivity issue (#5342)

* Throttle connectivity check on connectivity issue

If Supervisor detects a connectivity issue, currenlty every function
which requires internet get delayed by 10s due to the connectivity
check. This especially slows down initial startup when there are
connectivity issues. It is unlikely to resolve immeaditly, so throttle
the connectivity check to check every 30s.

* Fix pytest

* Reset throttle in test and refactor helper

* CodeRabbit suggestion
