Complete cli tools logging

This pull request enables ALL, correct me if wrong and I'll fix it, `cli` tools to be logging tweakable from the console.

Tools that originally were not supposed to have any console logging output, `salt`, `salt-cp`, etc, explicitly ignore the `log_level` setting from their configuration file which was originally used to configure the master and/or the minion.

To tweak the cli log level setting on the configuration files there's `cli_<underscored_cli_tool_name>_log_level` and some other settings too, see #5647
