Cleanup session on delete

If an external http connection was not passed into the client, we
create one with a requests.Session() on our own. Once this is used,
it may still have an open socket when the connection is closed. We need
to handle the closing of the requests.Session() ourselves if we created
one. If you do not close it, a ResourceWarning may be reported about the
socket that is left open.
