Add safety code for removed Update Control feature

Description

Acceptance criteria:

  • Add UpdateControlMaps key to our list of database keys like in Golang.

  • Upon startup, the key must be removed from the database if, and only if, there is no deployment ongoing (see StateMachine::LoadStateFromDb function).

  • If the key exists when loading deployment data, then this triggers an immediate deployment failure.

    • Make sure that log message explains that Update Control in both the deployment in the UI, as well as local applications, must be disabled.

  • Unit test

    • Most likely in state_test.cpp.

    • Make sure it is triggered after a reboot, which is the most likely scenario where it would occur for real.
