Anyone working on HTTP/2 in apache2 charm?

[Robie Basak]

Hi Robin,

With HTTP/2 support no longer experimental upstream, it does sound like
we can get this enabled in Xenial now. I've added this task to our
team's backlog. I don't expect this to get looked at before Artful's
feature freeze. If it needs a higher priority, please consult David
(added to Cc).

Thanks,

Robie
