Remote Container Adapter for WLP 8.5

First crack at creating a remote adapter for WLP, tested against WLP 8.5.5.4
Woohoo! I've been able to now run my first successful test using the adapter! - Problem was that the write failed of the archive failed on the remote server with the following error because the serverName in the arquillian.xml did not match my local server name:

```
[12/26/14 17:55:28:942 CET] 0000002f id=         com.ibm.ws.jmx.connector.server.rest.helpers.ErrorHelper     > createWebError Entry  
                                                                                                               java.io.IOException: CWWKX0121E: Access
 denied to path /home/gpoul/bin/wlp-8554/usr/servers/defaultServer/dropins/test.war.
```

Unfortunately this error is NOT logged by Liberty, but is silently ignored and 400 returned. - Maybe there is something in the content of the error as well; we should investigate this a little further to see whether we can not only throw the exception regarding the error code but maybe also include some additional information returned by the server. - If there is nothing conclusive in the 400 returned we should also go back to IBM to get this handled appropriately in a future version.
