[test] Cleaner namespace assignment.

[face_detector][test common] Fix warning in .launch format.
Fix namespace in testcases.
Increase retry. .bag-based perceptional tests are hard to deterministic, so it makes sense to do this.
Set param use_sim_time.
[face_detector][test] hztest can be used for measureing no publishment. hzerror is not needed in that case.
[face_detector][test] Specify test name. Pass all args.
[face_detector][test] pass_all_args might require all args kept out of include tag.
[face_detector][test] Specify test-name.
[face_detector][test] Disable all tests other than rgbd. I couldn't figure out how to use launches other than face_detector.rgbdlaunch, after hours of trial on local machine. I leave that up to someone else.
[face_detector][test] Detection using rgbd works with this config.
[face_detector][test] Shorter test duration (bag files are less than 7 seconds).
[face_detector][test] Shorter test_duration. We only need a second or so as long as we can confirm the designated topic is being published.
[face_detector][test] rosbag play with clock and loop option.
