Common subcommands for all defaults. - Closes #384. - Replaces `registry default` and `system dns default` subcommands with `system property`. - Users can use `system property ls` to see details about each supported default value. - `system property set` implements reasonable validation for all properties. - NOTE: Probing of the registry for `registry default set` was removed, which means users will find out about a botched setting when pulling or pushing. - Updates docs. ## Type of Change - [ ] Bug fix - [x] New feature - [x] Breaking change - [x] Documentation update ## Motivation and Context See #384. ## Testing - [x] Tested locally - [x] Added/updated tests - [x] Added/updated docs
