Guideline Never Log Level Info Or More In Execution Path

Never Log Level Info Or More In Execution Path

There should be no "trivial" logs in the normal execution path (see Logging in Python and EventLogger).

Existing Log Levels are:

def severity_string(severity, mapping={
    -300: 'TRACE',
    -200: 'DEBUG',
    -100: 'BLATHER',
       0: 'INFO',
     100: 'PROBLEM',
     200: 'ERROR',
     300: 'PANIC',
    }):
    """Convert a severity code to a string."""
    s = mapping.get(int(severity), '')
    return "%s(%s)" % (s, severity)
