feat: Add a startup script delay to annotated domain controllers

[glattercj]

Adds a wait loop in the windows startup script if this annotation is added:

      annotations:
        phenix/domain-controller: "true"

The wait loop specifically waits for the Get-ADDomain command to return, meaning the machine has fully booted and active directory services have started. Without this delay, the DC machine may enter a reboot loop.

@glattercj looks good to me. Is there a specific reason you have it marked as draft? Are you still doing some testing?

Also, can you maybe add something to the documentation about this? We probably need to add a section on annotations so we can document this and some of the other Windows-specific annotations we have.
