QA steps to verify

Testing enabled / opt-out:
1. Turn on new tab devtools: Set `browser.newtabpage.activity-stream.asrouter.devtoolsEnabled` to `true`.
2. Navigate to about:newtab#devtools-ds
3. Make sure the enabled checkbox is checked. Ensure discovery stream is visible on another tab.
4. Go to about:preferences#home and click the "Turn off discovery stream" button.
5. On about:newtab#devtools-ds, ensure that the enabled checkbox is now unchecked and you see the message "(Note: User has opted-out. Check this box to reset)" next to the checkbox.
6. Check the enabled box. Ensure that discovery stream now shows up again on a new tab page and the opt-out message has disappeared next to the checkbox.

Testing layout variants.
1. On about:newtab#devtools-ds, ensure discovery stream is enabled.
2. Check the "basic" radio box. Ensure you see a 3-card layout on new tab.
3. Check the "dev-test-all" radio box. Ensure you see a long layout with many elements.
4. On about:config, try changing the `browser.newtabpage.activity-stream.discoverystream.config` pref to include `layout_variant=basic` in the endpoint.
5. Check that on about:newtab#devtools-ds the basic radio checkbox is now checked.

There has been some confusion about the opt-out pref and changing the pref in general. These tools will make it easier to test Discovery Stream from the devtools ui at about:newtab#devtools-ds.

Iteration: --- → 67.1 - Jan 28 - Feb 10

Fyi, clicking "enable" from devtools cancels opt out.

Not critical for uplift, although it would be nice for QA to be able to test more easily...
