Better enforce the schemas in the api

[fretchen]

Is your feature request related to a problem? Please describe.
The schemas in the storage_provider can be enforced much better. Currently we only type hint to a dict for get_backend_dict, upload_status, get_status, get_result, backend_dict_to_qiskit

Describe the solution you'd like
We have plenty of pretty clear Schemes in the Schema file. In Alqor-UG/qlued#216 we have tested how we can be much more specific on those.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Additional context
This should really allow us to be cleaner on types and information that is send around.

We should hence to:

• upload_status
• upload_job
• get_job_content
• get_status
• update_in_database
• get_result
• backend_dict_to_qiskit
• get_backend_dict
• ExperimentDict
• add_job
• get_dict_from_list
• check_json_dict
• check_dimension
• check_experiment

Let's see how far we can get with this...
