Create parameter decorator shortcuts for the object type

[jannyHou]

Description / Steps to reproduce / Feature proposal

Inspired by issue #100.

We should create decorator shortcuts for object parameters from:

• query
• header
• path

The shortcut should be able to infer the schema from the type metadata.

For example:

import {Note} from '../models'
class MyController {
  @get('/test')
  async test(@param.query.object('note') note: Note) {
    // your code
  }: void
}

Acceptance Criteria

• create shortcuts
  • @param.query.object

NOTE: Objects are rarely if ever passed in via a path parameter or header as such those decorators are not to be added as part of this task. If someone decides to pass them via those areas, they can do so using the full @param decorator.

@jannyHou , I'm thinking this is post GA since it's enhancement on the developer experience or convenience. what do you think?

This was discussed during estimation and agreed to be a post-GA task.
