[FR] Enable Case Creation via API

[Deniz]

My FR is similar to: [FR] Enable Module config via API #149

Is your feature request related to a problem? Please describe.
Currently we are deploying DFIR. Fron our Opensearch we want to add Cases over API in IRIS ( http://127.0.0.1:8000/manage/cases/add).
Currently this requires a CSRF token to make those API calls as opposed to just having an API token.

Describe the solution you'd like
Is there or will there be any API which allows the Creation of cases with only the API Token?

Describe alternatives you've considered
I don't know sadly...
