Finalize fast-reboot in warmboot finalizer (#14238)
- Why I did it
To solve an issue with upgrade with fast-reboot including FW upgrade which has been introduced since moving to fast-reboot over warm-reboot infrastructure.
As well, this introduces fast-reboot finalizing logic to determine fast-reboot is done.

- How I did it
Added logic to finalize-warmboot script to handle fast-reboot as well, this makes sense as using fast-reboot over warm-reboot this script will be invoked. The script will clear fast-reboot entry from state-db instead of previous implementation that relied on timer. The timer could expire in some scenarios between fast-reboot finished causing fallback to cold-reboot and possible crashes.

As well this PR updates all services/scripts reading fast-reboot state-db entry to look for the updated value representing fast-reboot is active.

- How to verify it
Run fast-reboot and check that fast-reboot entry exists in state-db right after startup and being cleared as warm-reboot is finalized and not due to a timer.
