The Python client, out of the box, does not appear to set a User-Agent header, which contrasts with the raven client which used to send something like raven-python/6.10.0. This is unfortunately causing us issues as a proxy in our infrastructure blocks requests from Clients that do not provide a UA header.

Some of the other implementations appear to allow the before_send hook to influence the transport layer, but not the Python library.

Is it possible to set this in the same way raven does?
