Save DB dump after warm/fast reboot (#8803)

Browse Source 
As a part of warmboot, redis database is dumped:
c97fe546e5/scripts/fast-reboot (L269)
However, this dump file is deleted, after it is loaded back into db post reboot.
The DB dump can be useful for debugging purpose, hence taking a backup of it can be useful.
Instead of deleting the dump, rename and keep the dump.
