make expansion panel height configurable

[charlie-elverson]

Bug, feature request, or proposal:

Proposal

What is the expected behavior?

Height of the mat-expansion-panel-header should be configurable.

What is the current behavior?

Repeating issue 5641, which was closed with a PR that didn't address the issue. PR 6643 addressed expansion-panel-header but not expansion-panel height

What are the steps to reproduce?

Providing a StackBlitz/Plunker (or similar) is the best way to get the team to see your issue.

Plunker starter (using on @master): https://goo.gl/uDmqyY

StackBlitz starter (using latest npm release): https://goo.gl/wwnhMV

What is the use-case or motivation for changing an existing behavior?

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

Is there anything else we should know?

I don't know whether I get your proposal right, but couldn't you simply wrap the expansion's content in a <div> and control the height of the <div>? I believe the panel will correctly follow the height of this wrapping <div>. Then you can enable scrollbars or anything else you want by styling this <div>.

Good point. I just went back and reread the original issue. I misread it to begin with and thought it pertained to the panel itself, not the header. My bad.
