You might also want to check:

The issue is when bringing up hosted-engine: all VMs come up but one (BigIP) and I am trying to see if there is way to bring it up without having to store the engine password (using the ovirt_vm API).

The HA services on the hosts are directly responsible only for
starting the engine VM.

All other VMs are handled by the engine after it's up.

Usually, the engine starts all VMs that are marked as HA.

Is this BigIP VM marked HA? If not, perhaps try to mark it so. There
might have been concrete reasons you (or your team) didn't - e.g. it
might rely on some other VMs to be up, or something like that.

There isn't, as part of the existing functionality of oVirt, other
than marking it HA.

I am pretty certain I heard (on this list?) about people having more
complex scripts to automate start of their env, with more complex
dependencies of VMs on other VMs. You might want to search the
archive. But generally speaking, I think they are doing more-or-less
what you are already working on.

Good luck,
