Fetch BIOS config with sum before entering wait mode

[Gerrit91]

When a supermicro machine gets allocated, we need to wait for sum command completion twice. This takes quite some time and ruined our one-minute machine provisioning time mark.

Theoretically, it wold be possible to fetch the BIOS config shortly before entering the wait mode, such that we only need to run the update command with sum during machine provisioning. I am not sure if this can be dangerous because the BIOS config needs to reflect the current state of the machine, but I am also unsatisfied that the sum tool is slowing us down + being super weird. Is there any reason why this must be during provisioning time?
