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)

Are you running from your bundle, via bundle exec rspec, binstubs such as bin/rspec, or something else?

Yeah, we should fix this elsewhere so you don't have to do this.

We can either put the require here or in the Gemfile or by removing the require => false.
    gem "vcr",              "~>2.6",    :require => false

Appliances don't get these non-appliance gems but I think it makes sense to put it in spec_helper.
