Change metadata on Critical high/low sensor errors

Feedback from the field shows it would be useful to
have information about the sensors that are too high
or low in the metadata rather than the type.

This is a free format metadata string field so that
the code that creates this error can put in whatever
metadata it thinks is necessary, ideally including
information about the sensor(s) in question.
