Add non-IU artifact repositories to the planner resolution #874
Given that units from non-IU locations are considered when resolving IUs, it may happen that units are contained in the resolution path, which are not contained by any repository. This may break previously functional target definitions. To resolve this problem, an in-memory artifact and metadata repository is created, based on the metadata of the non-IU locations. Those repositories are then added to the provisioning context for further processing. Amends dd321b5
