Allow protocol to be set per endpoint-type
Allow protocol to be set per endpoint-type

If services are running behind an SSL terminating LB you will want to
differentiate between protocol on internalURL and publicURL endpoints.
This patch allows you to set the values of protocol per endpoint type,
but doesn't change the default behaviour which is to have it set in one
var.
