Description
#### Bug, feature request, or proposal:
Feature Request
#### What is the expected behavior?
I have some way of being notified when material animations (such as opening/closing expansion panels) have finished
#### What is the current behavior?
There is no way to know when animations have completed
#### What is the use-case or motivation for changing an existing behavior?
Opening a connected CDK overlay (eg. a tour walkthrough) before the animation has completed can result in incorrect positioning of the overlay
#### Which versions of Angular, Material, OS, TypeScript, browsers are affected?
5.0.0
#### Is there anything else we should know?
Contributor guide
Research direction
Start by tracing Angular Material animation handling for expansion panels and the CDK overlay positioning flow. Determine where animation completion could be exposed and how consumers would be notified. Done means callers can reliably know when a material animation has finished, so connected overlays can be positioned after the transition.
