java: directories as servlet

Allow the directories (capabilities and channelurl) to be deployed in a
servlet engine, as opposed to starting them as stand-alone Java
applications. Communication is then direct to the servlet and not via the
bounceproxy.

cpp: Reduce discovery timeout in tests

During tests, if discovery fails, the timeout is waited before the test
fails. Currently this timeout is quite huge (40 secs). So if a test fails
during arbitration it takes a lot of time until the test ends.

Now the timeout is set to 1 second, because all the test run locally.
