Add missing methods to Http2ConnectionHandlerBuilder

Motivation:
A previous commit added methods to AbstractHttp2ConnectionHandlerBuilder but forgot to expose them in Http2ConnectionHandlerBuilder.

Modifications:
- expose the new methods in Http2ConnectionHandlerBuilder

Result:
Http2ConnectionHandlerBuilder supports the new configuration options.
