REST endpoint for COVID calculator
Instead of using a voila dashboard for the COVID calculator, we have chosen to use a simple HTML based form, with a RESTful endpoint to return the model results.
In order to achieve this, we need a POST endpoint which allows us to send over our desired parameters, and return the key results from the model.
This ticket is to define the JSON payload that should be sent to the endpoint at /calculator/api/calculator
(via POST). This should be implemented in HTML by #36 (closed) and processed on the Python side at https://gitlab.cern.ch/cara/cara/-/blob/adfd4058d9aa6f3c881d2298040f47ffc2a0efbf/cara/apps/calculator/__init__.py#L9.
