Issue DM-2440: iRODS test:  Virtual collection 
iROD manages data as a 'virtual collection', that is, one can have a single logical/virtual view of a collection of files (the appearance of a single file system/tree) while the data with the collection is stored on separate physical servers. We demonstrate this by creating a collection with data targeted/uploaded to different physical resources.
