This is a stop-gap approach to remove the AtlasKit notifications stack.

Instead of using a AK FlagGroup to render our notifications (Flag components)
in, create our own container and use a fake FlagGroupContext provider, which is
what FlagGroup uses to control what flags can be dismissed.

Since we now render all notifications, the web part has been refactored to make
sure all notifications get a timer.

Passing around of the component was used when there were two
independent Notification components. Now that there is only
one Notification component, it is not necessary to pass
around the component.

It's not supposed to go on top of everything, like an error would. It's tied to
a conference, so render it outside of the OverlayContainer.

Prepare for React 16.

- Create a notification component for displaying a toggle.
- Create an action for showing the component if allowed by
  the local storage setting and for saving the setting to
  local storage.
- Remove all notifications having a timeout by default so the
  device error notification must be dismissed manually.
- Split the camera and mic error dialog into two separate
  notifications.
