test-https: test basic functions of client certificate authentication

Because hgweb doesn't support client certificates, I just patched it to
require client certificates that are signed and verified by the server
certificate. This won't be ideal for production servers, but should be okay
for the test.

The encrypted key file will be used by future patches. I couldn't figure out
a way to redirect a password prompt provided by OpenSSL, so it isn't tested
for now.
