Proposed changes

Accept values provided to flags, which are related to passwords, to start with a hypen (to prevent cli parsing errors).

Only the password related flags were allowed for this, as other fields didn't make much sense starting with a hypen anyway.

The following commands should now work:

tedge cert download c8y --one-time-password "-example1234"
tedge cert upload c8y --password "-example1234"
