SSL refreshes

ipkn#319, ipkn#269

I've run into this problem myself (while testing SSL file transfer), although it doesn't happen all the time, and seems to happen randomly for me.

ipkn#347 is a possible fix
Edit: While i do believe the PR above is useful, it does not fix the SSL refresh issue, more research needed.

Update: testing with a simple hello world route, issue consistently occurs 5 seconds after the last request (5 seconds is the default timeout time)

ipkn#347 seems to cause an infinite loop.

normal test: run firefox and insomnia rest, call crow from firefox, wait 5+ secs, call again, get SSL_ERROR_INTERNAL_ERROR_ALERT, call from insomnia, wait 5+ secs, call again, works as expected, no errors.

PR 347 test: exact same except app goes into infinite loop 5 secs after insomnia call.

The problem could be due to me shutting down the stream and socket unlike the PR : Edit: Testing shows it is because I shut down SSL, although fixing that the original problem persists.

It's worth mentioning that all of this can be avoided by just running crow behind a proxy like Nginx, but that would be running away from the problem.

Ok so building on the answer in ipkn#269, I was able to fix the bug by setting the verify mode to verify_client_once, this is a compromise from the suggested verify_none, although I have not researched the security implications, especially on websockets.
