## Issue
6366 Recsys Evaluation Telemetry
The recommended list from lighthouse is obtained from `makeSelectRecommendedContentForUri`. This list is further tweaked by the GUI (e.g. move autoplay next item to top, remove blocked content, etc.). Recsys wants the final recommendation list and the clicked index (in exact order), so we need pass these info to the videojs recsys plugin somehow. Also, Recsys wants a recommendation list ID as well as the parent (referrer) ID, we so need to track the clicks and navigation.
## General Approach
- It seems easiest to just spew back the final (displayed) list and all the required info to Redux, and the recsys plugin (or anyone else in the future) can grab it.
- Try to touch few files as possible. The dirty work should all reside in `<RecommendedContent>` only.
## Changes
- `ClaimPreview`: add optional parameters to store an ID of the container that it is in (for this case, it is `ClaimList`) as well as the index within the container.
- When clicked, we store the container ID in the navigation history `state` object.
- For general cases, anyone can check this state from `history.location.state` to know which container referred/navigated to the current page. For the recsys use case, we can use this as the `parentUUID`.
- `ClaimList`: just relay `onClick` and set IDs.
- `RecommendedContent`: now handles the uuid generation (for both parent and child) and stores the data in Redux.
- The `rateChange` event now logs the updated speed,
not just the time at which it occurred.
- The `scrub` now (more) accurately logs the position
it came from before the destination.
- The recsys events get consolidated for logical consistency.
## Issue
One of the items in 5865 Video shortcut issues
This one is not really an issue, but it would be nice to match what the arrow keys are doing. Also, in slower regions, seeking 10s will almost always end up buffering.
Also restores the CSS for vjs-overlay which I commented out previously for *some* reason (but I don't know why, and it doesn't seem to make a difference whether I comment it out or not)
Adds custom video.js hls quality selector plugin
This allows the quality selector plugin to stay active and listen for source changes on the player to prevent the need to recreate the player when switching between MP4's and M3U8's
## Issue:
5119 "Video: Mobile UI + overlay for keyboard shortcut feedback" was disabled because the feature broke the chromecast button in Android Chrome
