[Hawkular-dev] [metrics] Consistent error replies from REST API

Hi, There's a growing portion of application code in the metrics REST API which returns errors (with whichever HTTP status) in the following form: ==== {"errorMsg": "blah"} ==== Whether this format is nice or suitable is not the purpose of this message. I just want to draw your attention to the fact that being consistent regarding error reporting is important. In this regard, I've added a new ExceptionMapper for org.jboss.resteasy.spi.ReaderException[2] instances. So now, not only application errors conform to the format above, but also errors coming from payload parsing.
