J Logan 449f1d23df Replace scattered defaults subcommands with system property. (#604)
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

## Motivation and Context
