Auto reload resource files in the a Sanic app

[erickguan]

Is your feature request related to a problem? Please describe.
When a Sanic app is in production, I use different configs for development, staging, and production. I use 3 YAML files to implement that. However, they are not tracked by auto_reload in the development environment. I would be happy to be able to see Sanic can restart when I change the config.

Describe the solution you'd like
It can be a helper API to register resources for auto_reload. importlib provides a semantic method importlib.resources.read_text. It does no more than read(, 'r'). It might be nice to hook with readers from importlib.

Additional context
Example app structure:

awesomeapp
| - config
   | - development.yaml
   | - staging.yaml
   | - production.yaml
| app.py
| __init__.py

Potential API signature:
sanic.resources.read_text(package, resource, encoding='utf-8', errors='strict')

Can you explain to me the thought process on the read_text?

It seems like what you are really looking for is a way to tell sanic to reload for anything in ./config.

Something like this?

app.run(auto_reload=True, include_dir="./config")

You are right about this. Your solution is much simpler!

@erickguan I am really glad that you suggested this. It is something that I think I have thought in my head many times would be really helpful to have.
