Create a new log level for Rook that is hidden from users. This is the
most verbose log level, and it is the level developers would like to use
to get debug logs that are important for debugging but that could leak
senstivie information like credentials in production use.
If a user sets their debug level to "TRACE", they will merely get
"DEBUG" level logs. Only if they set "TRACE_INSECURE" will they get
trace logs, and those are likely to include insecure information. Rook
tries very hard not to leak sensitive information in logs even with
verbose "DEBUG" logs.
