Auto-refresh does not work on dashboard and visualize

[thomasneirynck]

On master, the auto-refresh of the time-picker does not cause a refresh on the dashboard and visualize page.

This does work properly on the Discovery page though.

This is a regression with the visualize refactor, which divorced Visualize from courier.

Responding to changes in the time-picker is currently implemented all over the place.

• courier listens on changes to the timepicker, and runs it's own loop https://github.com/thomasneirynck/kibana/blob/0d502aec49d8191e49974f215b3c35f9c0207b1b/src/ui/public/courier/courier.js#L130-L130
• Timelion also has its own implementation:
  https://github.com/thomasneirynck/kibana/blob/4c7022a725b9dcd4295c4c980c625a61bad86941/src/core_plugins/timelion/public/app.js#L181-L181
• TSVB also has its own refresher:https://github.com/thomasneirynck/kibana/blob/d8d65526c6afba0e12cbc39fe844ec0a3fb9ba95/src/core_plugins/metrics/public/services/executor_provider.js#L77-L77

The reason Discover works is because it relies on courier.

Visualize - after the refactor - should have its own refresher (triggering a reload event on every tick). This should replace the refresher from TSVB (and perhaps Timelion). Alternatively, we could make this optional, so individual visualizations can opt-in/opt-out of the auto-refreshing functionality.

Also consider that this timing loop should run in the timepicker component itself (https://github.com/thomasneirynck/kibana/blob/5c075f2a3f4eb3bebd2ec7a105b5a03ff8abe292/src/ui/public/timepicker/timepicker.js#L210-L210). That way, all clients of the timepicker can listen to an auto-refresh event. Right now, this logic is flipped.
