Introduce the `drop_unused_requests` option (False by default). If True, it will force the `Cassette` saving operation with only played old interactions and new ones if they exist. As a result, unused old requests are dropped.
Add `_old_interactions`, `_played_interactions` and `_new_interactions()`. The `_old_interactions` are previously recorded interactions loaded from Cassette files. The `_played_interactions` is a set of old interactions that were marked as played. A new interaction is a tuple (request, response) in `self.data` that is not in `_old_interactions` list.
The initial technique to implement `record_on_exception=False` was to
not emptying the generator returned by
`CassetteContextDecorator._patch_generator` when an exception happens to
skip the `cassette._save` call, however this had the side effect of not
emptying the `ExitStack` created inside the generator which contains the
`_patch.__exit__` calls to remove the patches.
This was innocuous in CPython, which uses a reference counting garbage
collector so the `ExitStack` was immediately collected after losing
scope and therefore its `__exit__` method executed.
Pypy, on the other hand, uses a generational garbage collector so its
objects may survive more time, enough for the `ExitStack` not called
until much later, which may cause the patches to live more than expected
when `record_on_exception=False`.
This was found because the test
`test_nesting_context_managers_by_checking_references_of_http_connection`
was failing because it was executed after
`test_dont_record_on_exception`.
Now the cassette instance is saved inside the `CassetteContextDecorator`
instance to have better control on where to save the cassette, and moved
the `cassette._save` call from the `_patch_generator` method to the
`__exit__` method to be free to empty the generator and remove the
patches always.

When no cassette exists, it's expected that the response returned, should be
the original, unchanged response. The response recorded in the cassette should be
that which is returned by the before_record_response callback.
But on subsequent requests/responses (when a cassette exists), the responses
returned should be exactly what is in the cassette.

Whilst working on the Reproducible Builds effort [0], we noticed
that vcrpy could not be built reproducibly.
This is due to the documentation including the absolute build path
via Python default arguments.
This was originally filed in Debian as #895269 [1].
