[ovirt] answer files: Filter out all password keys

Instead of hard-coding specific keys and having to maintain them over
time, replace the values of all keys that have 'password' in their name.
I think this covers all our current and hopefully future keys. It might
add "false positives" - keys that are not passwords but have 'password'
in their name - and I think that's a risk worth taking.

Sadly, the engine admin password prompt's name is
'OVESETUP_CONFIG_ADMIN_SETUP', which does not include 'password', so has
to be listed specifically.

A partial list of keys added since the replaced code was written:
- grafana-related stuff
- keycloak-related stuff
- otopi-style answer files
