- Focus of these changes are to introduce a new command system based on
real registrations (new way) instead of continuously (old way) resolve
methods and its parameters via reflection.
- There's a lot of changes as this resolution via reflection had its
hooks almost everywhere and thus most changes are just refactorings.
- Order to understand real changes I'd start to look classes under
`org.springframework.shell.command` package as it defines new registration,
catalog and parser classes. Also samples contain new classes to demonstrate
new functionality.
- Fixes#380
