Add INIT_ALLOWED_IPS for unattended setup (#2164)

* Add INIT_ALLOWED_IPS env var

Implement INIT_ALLOWED_IPS env var like the INIT_DNS to preset the global Allowed IPs field.

* Docs: Add INIT_ALLOWED_IPS var to unattended setup table

* Make UserConfigService.update param partial

Update UserConfigService.update() to accept any subset of the updatable fields.
Remove the unnecessary userConfig object from  DBService.initialSetup()

* formatting fix

* format on linux

On windows prettier get confused by global conf... common windows things
