Reduce logging

[Rezenders]

Too much logging going on, it is impossible to read anything.

@Rezenders do you know the following is possible?

ros2 run package node --ros-args --log-level DEBUG --log-level rcl:=INFO

This sets loglevel to DEBUG for all except for rcl.

You can add also others, e.g.:

ros2 run package node --ros-args --log-level DEBUG --log-level rcl:=INFO --log-level rclcpp:=INFO

Or, you can set the loglevel for one (or more) loggers specifically, e.g.:

ros2 run package node --ros-args --log-level FATAL --log-level my_logger_name:=DEBUG

If this solves you problem, please close this issue.
