Warn instead of exit when new protocol live date is exceeded

[RdeWilde]

Is your feature request related to a problem? Please describe.
Currently the application implements a hard cut-off date when the new protocol should be live. When running in non-interactive mode, this will cause our containers to crash-loop (obviously when there's no updated release before the deadline).

Describe the solution you'd like
Make it (an option) to warn about the deadline, but not crash. Although the purpose of the check is clear, we don't want our containers to crash.

Describe alternatives you've considered
Forking the repository and changing the deadline date manually or remove the code to exit the program
