Description

Depends on #2172.

  • If no_save is True, then the option is not saved with the opt.
  • If no_override is True, then the parser will throw a hard error if the value on disk is not what's loaded. This one might have to wait a bit longer.

Contributor guide

Research direction
Study the current ParlaiParser implementation and the referenced issue #2172. Add the 'no save' and 'no override' parameters to the add argument method, ensuring that 'no save' prevents the option from being saved in opt, and 'no override' raises an error if the disk value differs. Write tests to verify the behavior.
