[virt-tools-list] [virt-install PATCH v2 03/14] osdict: Add get_install_script_config()

[Fabiano Fidêncio]

get_install_script_config() method returns an OsinfoInstallScriptConfig
object that's tied to an OsinfoInstallScript object, already configured
based in the info provided by the user and it's ready to be used.

For now, the config will always set the timezome to 'America/New_York'
and the language and keyboard layout to 'en_US'.
