Commit Message

Add decorator for mocking http responses (#3112)

### Summary

Add a `@mock_responses` decorator that allows a test to use mocked
responses against the API. It is based on `responses`, providing a
slightly customized `BaseRegistry` for specifying which instances and
backends are to be available in the test (and generating the responses
based on those).

A couple of test files have been revised in order to make use of the
decorator.

### Details and comments

Fixes #3109

The intent is not to extend the decorator/registries functionality to
cover all API usage, but instead to allow comfortable testing of
`QiskitRuntimeService`, and specially its instance/backend
functionality. If this goes through, the plan is to continue revising
the unit tests to convert them to this approach, being selective (as
there is the risk of increasing complexity in the callbacks).
