The `defaultLogLevels` are the log levels passed with `TwillPreparer`, when
resetting the log levels, we will need it to update the live node info to
indicate the log levels. The `oldLogLevels` is the same as the
`defaultLogLevels` when the runnable starts up. We will not update it for each
log level change. It is used to save old log levels for loggers for the first
time change as we do not know what is in the `logback.xml`. When reset, we
reset based on this map.
