Add command-line tools for Registry.certify and Registry.decertify.
These methods are being added on
DM-24432, so that's a blocker for this ticket.
These scripts will need to start with a call to Registry.queryDatasets, and so will build on the script for that; I'll add
DM-26685 as a blocker, too.
I'm calling this a blocker for Gen2 deprecation because I think it's an important part of the CPP workflow. But it's possible Christopher Waters or myself will write command-line tools that call these Registry methods as well as doing other things, and that would at least reduce the priority of this ticket.
