This function will be used in the next commits to allow the user to
ask fsck to handle specific problems differently, e.g. demoting certain
errors to warnings. It has to handle partial strings because we would
like to be able to parse, say, 'missing-email,missing-tagger-entry'
command lines.
To make the parsing robust, we generate strings from the enum keys, and
using these keys, we will map lower-case, dash-separated strings values
to the corresponding enum values.
