[devtool-testlib] add deprecated entry point for publish method 6c2119509fac renamed ``publish`` to ``handle_request``. And removed the older testlib function (because the semantic of handle_request is quite different from the publish one). However it seems to do more harm that good and I'm adding proxy with deprecation warning for those.
