Moves the license compliance reports to the BE

- Adds actions and mutations to fetch the new endpoint
- Conditionally fetches the old or new reports dependant on a feature
flag
- Tells the LC getter to fetch the new report if it's there, and the old
one if not.
- Adds a bit of a hack to morph the new data in to the old format
(temporarily)
- Pulls in the proper polling endpoints
- Adds tests for all the above
