Issue 50746 - Add option to healthcheck to list all the lint reports
Bug Description:
Healthcheck lacks a way to find out what checks are available.
Fix Description:
Add dsctl healthcheck options to list available checks, known error
codes, and ability to run cehcks selectively. The checks are rather
hierarchically structured and in some cases matchable by patterns (by
use of asterisk).
