Feature/update documentation

Update documentation

• use rst files instead of markdown
• no more autodoc2, fully replaced with autodoc
• updated the documentation, so less output from Vale or Sphinx (warning-wise)

-# Quickstart
-
-## Development environment and dependencies
-
-- Install python 3.10 if you don't have it already:
-	- ``add-apt-repository ppa:deadsnakes/ppa``
-	- ``apt install python3.10 python3.10-distutils``
-- Follow Steps 1 and 2 from here to install dependencies and setup DB: https://workfloworchestrator.org/orchestrator-core/workshops/beginner/debian/
-- To install the orchestrator GUI, you can follow the steps 5 and 6 from the previous link.
-- Create a virtual environment:
-	- ``source /usr/share/virtualenvwrapper/virtualenvwrapper.sh``
-	- ``mkvirtualenv --python python3.10 gso``
-- To use the virtual environment:
-	- `source /usr/share/virtualenvwrapper/virtualenvwrapper.sh`
-	- `workon gso`
-
-## Installation
-
-Do all this inside the virtual environment.
-- Clone this repository and ``cd`` into it
-- ``pip install -r requirements.txt`` 
-	- If you get an error because you pip version is too old, run this: `curl -sS https://bootstrap.pypa.io/get-pip.py | python3.10`
-- ``pip install -e .``
-- `cd` into `gso` directory and create ``oss-params.json`` based on the ``oss-params-example.json`` file.
-- Export the oss-params file: ``export OSS_PARAMS_FILENAME="/path/to/oss-params.json"``
-- Upgrade DB to latest revision: `PYTHONPATH=. python main.py db upgrade heads`
-
-## Run
-
-- Start the workflow orchestrator core with ``uvicorn --host 0.0.0.0 --port 8080 main:app`` from inside the ``gso`` directory of this repository.
-- Start the GUI with ``yarn start``.

-### API examples
-
-*Note: update IP address in the request to your own where you're running WFO.*
-
-**Creating subscriptions** (look at the `initial_input_form_generator` method of the workflow to find what properties need to be in the body of the POST request)
-
-Create process that produces a new subscription (CREATE workflow)
-
-``curl -X POST -H "Content-Type: application/json" http://10.98.1.62:8080/api/processes/create_trunk --data '[{"product": "321045fc-21ec-476b-b67b-5f211e47c3d7"},{"trunk_name": "mytrunkfromapi", "geant_s_sid": "a1b2c3"}]'``
-
-Create process that manipulates the state of a subscription (TERMINATE workflow)
-
-``curl -X POST -H "Content-Type: application/json" http://10.98.1.62:8080/api/processes/terminate_trunk --data '[{"subscription_id": "910e7044-c427-46d1-afc3-7817e221d45d"}, {"are_you_sure": "yes"}]'``
-
-**Deleting subscriptions** (not the same as running a TERMINATE workflow for a subscription, but to actually erase it from the WFO database)
-
-To do this, you first have to delete the processes first:
-
-``curl -X 'DELETE' 'http://10.98.1.62:8080/api/processes/7447a3e9-7c58-4ae7-8804-c0a75c39c924'``
-
-Delete a subscription:
-
-``curl -X 'DELETE' 'http://10.98.1.62:8080/api/subscriptions/3f16532b-0a48-4fe3-802a-36b3f54eed0e'``
