DDSJAVA — QoS DSL Needed

The absence of a DSL for facilitating the correct creation of QoS (in QoS classes such as:
TopicQos, DataWriterQos, etc.) in the
dds-psm-java not only makes QoS manipulation cumbersone, but it also
introduces potential for errors.

[Resolution]
Define a QoS DSL for the dds-psm-cxx which might look like this:

TopicQos topicQos =
(new TopicQos())
.with(Reliability.Reliable(), Durability.Transient());

This is also legal:

TopicQos topicQos =
(new TopicQos())
.with(Reliability.Reliable())
.with(Durability.Transient());

• These class should implement the Comparable interface as they need to
  provide a total order... Otherwise how can one do RxO?
