These tests are fragile and timer based. They're relying on animation completion and timed cleanup. The update to auto cleaning the container means that we've destroyed the container and it breaks the way this was intended to be tested.

Add in the concept of relation collections to store multiple relations between two services in a single object, allowing for a menu to display the individual relations separately.

To QA:

* run make devel, visit 0.0.0.0:8888/:flags:/relationCollections
* add hadoop, add hadoop again as hadoop1, add mysql, add mediawiki
* relate mysql and mediawiki; should look fine; should be able to delete relation by clicking on relation indicator (currently a circle)
* relate hadoop and hadoop1 twice, in multiple ways; should only see one line (right click on indicator, inspect element, should only see one .rel-group); should be able to delete *twice* (deleting specific relations coming soon with menu, but for now, deletes in order created).
* no errors on console with general QA
* no errors in tests.
