Build slice from indexed data in SliceProvider

Connect the SliceIndexing data to the SliceProvider,
such that a query to SliceProvider can build a Slice
via the indexed data from SlicesIndexingManager.

We take the key from the Uri supplied to the SettingSliceProvider
and find a potential matching row in the indexed data. The
matched data is then used to Build a slice for the caller.
