setup password for internal database config

## We need to set postgresql database password, and fix postgres network connectivity

- appliance_console: internal database prompts for password.
- CentOS kickstarter: pass password into appliance_console_cli
- appliance_console_cli: relay username/password/databasename
- postgres: prompt passwords on all network connections (ident not installed)

How do we bypass the asking of questions for internal DB for the nightly build?  Won't it still ask for the password?
