feature: ability to call ion-refresh programmatically

Ionic version: (check one with “x”) [ ] 1.x [x] 2.x

I’m submitting a … (check one with “x”) [ ] bug report [x] feature request [ ] support request => Please do not submit support requests here, use one of these channels: https://forum.ionicframework.com/ or http://ionicworldwide.herokuapp.com/

Current behavior:

There seems to be no API to programmatically start the loading of the refresher. It would be awesome to use the refresher to also show the user that some content is reloading, e.g. if the app is resumed. Additionally it does not make sense to use another component (like the LoadingController) if the refresher is used on the page anyhow – if there are two different components that basically indicate the same thing (which is reloading content) it could possibly confuse the user.

Expected behavior:

Steps to reproduce:

@karx - the feature requests repo is a private repo.

At this time, no feature requests are being worked on until after the next major release of Ionic and Ionic for Angular are complete.

There has also been some talk of perhaps managing feature requests differently at that time, but nothing has been determined on that front yet.
