API-based components

[caviri]

Context
API-based components are needed in order to have a proper microservice based execution. These components will perform small tasks by performing a request to the API endpoint.

Possible solution

• Use FastAPI to generate semi-automatically an API endpoint based on odtp.yml. The user will define a bash script that will run every time that the api is called. This run will follow the same structure of an ephemeral component. A temporary folder will be generate where to place the input/output files needed.

As a result of the run, the API could provide directly the output via JSON or via an URL to an output object stored in Minio.

Acceptance criteria

• odtp-.yml parsing and API generation of ODTP component via odtp-component-template
• FastAPI-based minimal example of ODTP component (odtp-component-example)
• Report on stress testing report on multiple calls and long tasks.
