Support for retrieving OpenAPI schema from URL

I'm currently trying to use the package in our Django test suite for an specific service, the thing is that we have all our schemas in a separated repository that's why we spin up that repository and we can access the schemas the different schemas for example like http://schema_repository:{port}/xyz_schemas/openapi.yaml.

When attempting to pass that path to SchemaTester I found out that it fails to find the file, and checking into the code I see load_schema only attempts to read from a file (

drf-openapi-tester/openapi_tester/loaders.py

Line 256 in ef24951

with open(self.path, encoding="utf-8") as file:

) (which makes us now to grab the files we need, store them, pass the path and remove them).

It would be ideal if load_schema could support also the possibility of retrieving the schema itself from an URL.

The library has a concept of "loaders". There is a file-loader, a drf-yasg-loader, and a drf-spectacular-loader. This sounds like a use-case for an "url-loader" or something along those lines.

In other words, I think it would make sense to write your own class to handle the case where you need to retrieve a schema from a URL. If you do, a PR is welcome; this sounds useful 👍

Here's the StaticSchemaLoader for reference. All you would need to do is write your own load_schema method which fetches the schema with a GET request.

@sondrelg thanks for clear guidance! I will submit a PR with this feature probably tomorrow then 👍
