Acceptance criteria

~~All artifact script execution and results must be recorded in persistent storage, so that a reboot will pick up where it left off~~
All states and transition context must be recorded in persistent storage, so that a reboot will pick up where it left off.
Upon starting, Mender must check which state it was in and rerun the state if it was not finished
the only guarantee given by Mender is that the state or transition that was currently in progress when the spontaneous reboot happened, will be rerun.
-> Thus the user will have to guarantee that all the functionality required in one state/transition is capable of operating independently of the other states/transitions.
Time that the script was first executed must also be recorded so that timeout may not be artificially lengthened by rebooting
