In HotRod, errors reading the header should not be hidden
---------------------------------------------------------

                 Key: ISPN-846
                 URL: https://issues.jboss.org/browse/ISPN-846
             Project: Infinispan
          Issue Type: Bug
          Components: Cache Server
    Affects Versions: 5.0.0.ALPHA1, 4.2.0.Final
            Reporter: Galder Zamarreño
            Assignee: Galder Zamarreño
             Fix For: 5.0.0.BETA1, 5.0.0.Final


If Hot Rod has an issue reading the header (for example, the cache name), the actual issue gets hidden in the logs:

2010-12-21 10:02:49,948 TRACE [HotRodEncoder$] (HotRodServerWorker-1-1) Encode msg GetResponse{messageId=1, operation=GetResponse, status=KeyDoesNotExist, data=null}
2010-12-21 10:02:50,100 TRACE [Decoder10$] (HotRodServerWorker-1-2) Operation code: 3 has been matched to GetRequest
2010-12-21 10:02:50,538 ERROR [AbstractProtocolDecoder$] (HotRodServerWorker-1-2) Exception reported
java.util.NoSuchElementException: None.get
	at scala.None$.get(Option.scala:262)
	at scala.None$.get(Option.scala:260)
	at org.infinispan.server.hotrod.HotRodDecoder.createServerException(HotRodDecoder.scala:138)
	at org.infinispan.server.core.AbstractProtocolDecoder.decode(AbstractProtocolDecoder.scala:55)

Add better error handling for such situations.

This came from trying to debug the Python Hot Rod client.
