Migrate to new Travis CI (container based) infrastructure

[jaapz]

I was working on my UWSGICache PR and saw that Travis CI was complaining that the werkzeug CI jobs are running on legacy infrastructure.

The exact warning:

This job ran on our legacy infrastructure. Please read our docs on how to upgrade

Which links to this documentation page.

I suppose that's because our travis config tries to install the latest pypy. I'm not sure if that's necessary.

I don't get this warning on other Werkzeug builds. God knows what Travis is up to.
