Attach the keywords used for Settings search to Slices. Their primary use is helping match synonyms for presenters which display slices without explicit Uri requests, like a launcher. This changes: - Updates database scheme - Adds to SliceData object - Grab keywords in the SliceDataConverter - Set keywords on all slices Test: robotests Change-Id: I16c40d2380ffddaf0a87fb1b9cd58e95573b308f Fixes: 78306195
