`SaltCMD`, ie, `salt` binary now support logging tweaking from the console.

Default log level is warning, though, since the master configuration file is shared, whatever the log_level defined on the master configuration file that's the value that will be used. To tweak the salt-run log level on the configuration file, independently from the master, you can use cli_salt_log_level(See #5609).
`salt-cp` binary now supports logging tweaking from the console.

Default log level is `warning`, though, since the master configuration file is shared, whatever `log_level` is defined on the master configuration file that's the value that will be used. To tweak the `salt-cp` log level on the configuration file, independently from the master, you can use cli_salt_cp_log_level(See #5609).
Check if `verify_env` is true.
Even for `salt-key` the log file setting should be checked to see if it's not directed to syslog.
