Generated C++ can't construct in a single line

[tmayoff]

This might be related to this issue, #38. For testing I like to setup my tests like this:

const std::vector<Testing::TestMessage> tests = {
      {uuid, 0, "testing", 0},
      {uuid, 1, "Test Message", 1414241},
      {uuid, 2, "Messaging Test", 1245265346},
      {uuid, 3, "Test", std::chrono::system_clock::now().time_since_epoch().count()},
  };

However due to the way the constructors are generated I can't, is it possible to update the constructors to allow this (maybe with some of the suggestion in the linked issue)

The same would be nice with the QoS policies. Although I'm not sure if these are generated from IDL

fastdds::DurabilityServiceQosPolicy{Duration_t{}, fastdds::KEEP_ALL_HISTORY_QOS, 1, 10, 10, 10}},

Moving the ticket to the Ideas discussion forum where enhancements and feature requests are discussed.
