Fixes for tests in service recording

[MichaelOrlov]

• Relates Implement service recording and display info about recorded services ros2/rosbag2#1480

List of fixes:

• Address flakiness in newly added rosbag2_transport tests
• Use wait_for_srvice_to_be_ready() instead of the check_service_ready()
• Add rosbag2_test_common::wait_until_condition(..)
• Rewrite get_service_info tests to be more deterministic
• Renames in the get_service_info tests
• Use std::filesystem instead of rcpputils::fs functions
  • Rationale: Deprecation of the rcpputils::fs in future
    See Deprecate rcpputils::fs in favor of C++17 std::filesystem ros2/rcpputils#164 for details
• Avoid extra metadata readout in ros2 bag info verb with --verbose
• Add info_end_to_end test with --verbose parameter

Thank you for your assistance.
I checked each one, and they look good to me.
About info.py, how about to output a warning while users pass '-t' and '-v' at the same time.

I merged them.

If you think it is okay, I will add it in ros2#1480.

Sorry for my late response. Yeah, with warning will be even better. 👍
