DDSJAVA11 — Operations with Collection as parameter should provide a "varargs" alternative

The use of Collection for providing a single "parameter" is rather cumbersome and could be greatly improved by providing a "varargs" alternative.

Here is an example that showcases the issue:
p = dp.createPublisher(
dp.getDefaultPublisherQos().withPolicy(
pf.Partition().withName(Arrays.asList("MyPartition"))
));

In this case a withName(String... names) operation will simplify the code as shown below:
p = dp.createPublisher(
dp.getDefaultPublisherQos().withPolicy(
pf.Partition().withName("MyPartition")
));

Moreover the use of Collection type could lead to compilation error as in the following case:

statusCondition.setEnabledStatuses(Arrays.toList(DataAvailableStatus.class));
