This PR should come along with sonic-utilities PR (sonic-net/sonic-utilities#2621) removing the timer usage from fast-reboot script and all other submodule PRs using the fast-reboot state-db entry:
sonic-net/sonic-swss-common#742
sonic-net/sonic-platform-daemons#335
sonic-net/sonic-sairedis#1196
This set of PRs solves the issue #13251
Why I did it
o 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
Which release branch to backport (provide reason below if selected)
