Support ordering of Project Notes in the Notes API

Description

Accept sorting parameters for Project's Notes API

Proposal

Sorting of a project's notes via the Notes API is not currently supported. Let's change this so that we can sort by created_at and get retrieve the results in order

Let's also support order_by for desc and asc

### Summary

I tried to query the REST API with /api/v4 for notes in an issue order_by created_at (or id) and sort asc. It did not work. All queries return same results 

### Steps to reproduce

Query any issue notes with /api/v4/projects/pid/issues/iid/notes?sort=asc&order_by=created_at

Try same with desc. See the result has no difference

### What is the current *bug* behavior?

Not sorting by given order

### What is the expected *correct* behavior?

Sorted as per given order
