Add a simple test to verify that the server will fail to start up when no valid
cipher suites are passed to `ssl-cipher`.
As different TLS libraries and versions have differing cipher suite support, it
would be a good idea to ensure the server behaves in a safe manner if it is
configured with invalid cipher suites.

Abort startup, if SSL setup fails.
Also, for the server always check that certificate matches private key
(even if ssl_cert is not set, OpenSSL will try to use default one)
