* Improve UX of HA CLI wrapper and emergency console For many users, the emergency console gives feeling that the system is completely broken. However, there are various cases when the system just takes just a bit longer to start up and the emergency message is shown, while it finishes a proper startup shortly after. This change tries to improve the UX in several ways: * The limit before a forced emergency console startup is changed to 3 minutes * Waiting can be interrupted with Ctrl+C (reset counter is cleared then) * Some hints what to check have been added before starting the shell * Also, because if the HA CLI failed for 5 times in a row in quick succession, the CLI startup was then not retried anymore and user may have been left with a black screen, the restart limits timeouts have been adjusted only to back off and never mark the unit as failed Closes #4273 * Use /bin/sh and printf to silence linter errors
