This reverts commit 608276b.

Looks like this breaks the backward compatibility of rllib (it is supposed to print warn first, but it prints the info log).

Attempts to consolidate logging configuration by introducing reasonable defaults in ray/log.py.
This new logging configuration is done once in ray/__init__.py at the top of the module. Subsequent calls to the configuration are ignored.
A logger for ray.rllib is configured at the WARN level, to address Revert "Simplify logging configuration. (#30863)" #31858. With this change,
Revert "Simplify logging configuration. (#30863)" #31858 can be reverted, again simplifying and consolidating logging configuration.
Modified test_output.py::test_logger_config to test only the logger config, not launch a ray cluster. The test was failing intermittently, I think due to a race condition between the launch of the cluster and the reading of the subprocess's stdout, and anyway it wasn't necessary to call ray.init here to check that logging was configured correctly.
Modified python/ray/tune/tests/test_commands.py::test_ls_with_cfg to test the underlying data, not what gets printed to stdout (which has changed with the new logging system).
Modified a logging message in ray.tune.automl.search_policy.AutoMLSearcher.on_trial_complete, which in certain cases emits a logging message which tries to format a NoneType into a %f during log message formatting. This was a previously-undetected bug which showed up because the default log level is now INFO. This fixes a test that was failing in test_automl_searcher.py::AutoMLSearcherTest.
