[wildfly-dev] HTTP/2 out of the box in Wildfly 10.1

[Jason T. Greene]

Awesome! Another idea I had on how we could get away with it being in server boot, is to have a pre-boot first time setup task, either launched from the shell/batch scripts or as a special pre-step before the AS module loads. We could then report boot time as the time AFTER first time installation tasks have completed, which I think is fair because the server hasn't yet been started.

I am not sure what other options we would need, or how configurable we should make it, but as this is for testing/development purposes I don't think we need to expose full control over the certificate generation process.
