* Initial attempt to remove labels and then rename properties to labels.

* Remove old v2 "labels" and "properties" and replace with new v3 "labels"

* Update the UI to merge labels and properties

* Fix broken UI tests

* Try to improve robustness of UI test

* Added test for legacy v2 API label/property support

* Update the default REST API endpoint in the UI config
