Alter framework logging.yml configuration

[antonymilne]

Various small changes to make to the framework kedro/config/logging.yml (not to the project conf/base/logging.yml):

• delete the section root
• add the kedro.io and kedro.pipeline that are in project conf/base/logging.yml to the framework kedro/config/logging.yml
• add the following to the loggers:

kedro:
  level: INFO
  handlers: [console, info_file_handler, error_file_handler]
  propagate: no

Do some kedro runs to make sure things look ok. I'm pretty sure they will.

Might fix the kedro-airflow problem, double check this is the case.

Slightly different, new and improved version of this in 83b074f:

• keep the root logger but no longer change its level to INFO (it will keep the default of WARNING)
• kedro logger just changes the level to INFO, which propagates to the root logger
• the only special case is kedro.framework.cli.hooks.manager, where we don't want to write to a file
