VID-1985 Add caching to getVideoDetail. Increase caching VM

Ah, we talked about this in our stand-up yesterday. We decided that since VideosModule content can change from us programming videos, new videos being added from ingestion, and perhaps most importantly, us needing to blacklist inappropriate videos that start showing up, caching for 12 hours would be a good compromise in giving us some timely control over the content while still making sure it's cached sufficiently.
