Add foreman_ygg_migration package

This package should get pulled in when yggdrasil >=0.4.z is installed.

When installed, it checks whether yggdrasild.service is enabled. If not, it
does nothing. If enabled, this package tweaks yggdrasil's config file to account
for the newly needed config options. Additionally, it disables the yggdrasild
service and enables yggdrasil.service.

Our worker is left to be activated through dbus.
