Bring elemental config generation methods

Brings the elemental-cli config generation methods so the installer
reads the config files for elemental and merges them back into the final
config.

This has the side effect of bringing viper as a dep as we rely heavily
on viper to unmarshall everything so maybe we should move the cli to use
viper
