injection_points: Add injection_points_list()
This function can be used to retrieve the information about all the
injection points attached to a cluster, providing coverage for
InjectionPointList() introduced in 7b2eb72b1b8c.
The original proposal turned around a system function, but that would
not be backpatchable to stable branches. It was also a bit weird to
have a system function that fails depending on if the build allows
injection points or not.
