Make _cassette_name a part of API

[jirikuncar]

Rename _ca(s)sette_name helper function to cassette_name to be a part of the API.

Why?

I am using it to define more advanced fixtures. I could try to make the current fixtures more configurable but it will complicate the codebase.

I genuinely don't understand your use case. What does "more advanced fixtures" mean?

[jirikuncar]

I have something along this lines in my client tests:

@pytest.fixture(scope="session")
def recorder():
    import betamax
    import client

    session = client.Client("http://localhost:8000")
    with betamax.Betamax(session) as vrc:
        yield vrc


@pytest.fixture
def session(request, recorder):
    from betamax.fixtures.pytest import _casette_name
    recorder.use_cassette(_casette_name(request, True))

    yield recorder.session

and I would like to make sure that _cas(s)ette_name becomes a public API.
