bravado.http_future.RequestsFutureAdapterConnectionError

I found it use bravado to send request, and it can use with ssl_verify after this pr. How could I use fuzz-lightyear with ssl_verify set?

Hi, I also faced with that issue and could not find right way to bypass it. Quick (but not elegant) way is to modify your local bravado library source code -- https://github.com/Yelp/bravado/blob/master/bravado/requests_client.py#L285 -- True --> False. But may be there is other more elegant way to do that.

@AlexB1986 I did the same way to fix it, I modify file in venv/bin.

Thanks.
