fix: Register plugin configs in echo (#16)

# Register plugin configs in echo

The plugin level configs were not registered in echo due to which the
endpoints registered via plugins were not working. This fixes the bug.


- New feature (non-breaking change which adds functionality)
- Bug fix (non-breaking change which fixes an issue)
