Add an --insecure / -k option to disable SSL certificate verification

When testing https to a test machine that has a self-signed certificate, it is handy to be able to disable certificate verification.

$ http https://192.168.4.137/test

http: error: SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:547)

vs:

$ curl --insecure https://192.168.4.137/test
... got what I was expecting here ...

You can do http --verify=no https://129.168.4.137/test, at least with the current master branch.

Yes, --verify=no does the trick.
