Correctly validating that AER and IBMQ support the methods and field types for every device and simulator

[jaygambetta]

What is the expected behavior?

This is related to #1047 but the difference is I want to have a way that I can easily see that the provider is a valid provider for terra.

The idea is that it should return data that passes the schemas

• backend_configuration_schema.json
• backend_properties_schema.json
• backend_status_schema.json Update backend.status() to use BackendStatus #1301
• default_pulse_configuration_schema.json (only internal for now)
• job_status_schema.json
• result_schema.json

Then I think terra needs to have some way to be sure that it is making a qobj that passes the schema

• qobj_schema.json

Then inside the IBMQ provider, we should have something that confirms that qobj from terra will work

• ibmq_device_qobj_schema.json
• ibmq_simulator_qobj_schema.json

Then we need something in the AER that does the same

• Aer_qobj_schema.json

Closing, only Qobj models left and let's track in a separate issue. @diego-plan9
