Make the SSH port parametrizable
Fix bug: serverPort parameter is already declared in other task, the field has been renamed to sshPort to avoid conflicts
Add the 'timeout' parameter to the run goal (global timeout in milliseconds for release tests).
Use JodaTime API to parse/print the global release tests timeout.
Bug fix in the method DefaultJavaExecutor.execute : a NullPointerException was thrown when the timeout is null.
Fix a a bug in parseDuration(String duration) and printTo(StringBuffer buffer, Duration duration) methods : using a null duration is considered as a normal use case and shouldn't throw an exception.
Specify a default value for timeout parameter and use the new maven format for this one.
