The idea is to massage the setup in a way to make implementation
of new configurations less error prone by identifying recurring patterns
and sharing repetitive code that tends to be forgotten (see Android cloning).
The former two lines of constructors (owner-and-id, owner-and-source)
are split into a simple, shared, constructor and new setId() and
copyFrom() functions.
The change is mostly mechanical, some multiple calls to fromMap
have been removed, though, some consts added.
Otherwise, to keep the patch small it temporarily introduces two
helper templates in IRunConfigurationFactory. Also, setId() signatures
have not been unified yet. These won't be needed in the final setup.
