CLI: Convert OpenAPI Spec to Models

[ElSnoMan]

poetry run pyclinic generate-models --input-file-type TYPE --input IN_FILE --output OUT_FILE

• If --input-file-type is "postman", then use our model generator
• else use datamodel-codegen

[ElSnoMan]

Currently, PyClinic comes with datamodel-codegen, so:

If the user needs to generate models from a Postman Collection

pyclinic generate-models --input-file [path/to/collection.json]

If the user needs to generate models from a Swagger spec, OpenAPI spec, generic JSON, etc.

datamodel-codegen --input [path/to/file] --output [path/to/save]
