ctingue b3b4bba9aa Align parameter formats for zone data commands
Seems silly that one command uses --tlds for the required parameter, while the other one doesn't.

As part of this change, create a DateParameter for commands that require only a date (i.e. a DateTime parameter restricted to midnight UTC).
