Add Manifest Property for Envoy Proxy HTTP/2

Summary

The HTTP/2 implementation from cloudfoundry/gorouter#289 added ALPN configuration to the Envoy Proxy's listeners. This could cause problems for clients other than Gorouter connecting through the Envoy proxy. To help operators manage this change, we added a manifest property that will allow them to disable the ALPN configuration.

• Defaults to HTTP/2 enabled
• When false, Envoy proxy sidecar will not advertise HTTP/2 support via ALPN
