Access to server using SSL isn't working.

The logic to check if the SSL private key is present looks to be inverted.

vanye ~/S/g/s/g/m/consul-cli ] ./consul-cli --consul 10.5.24.1:8500 --ssl --ssl-ca-cert ~/SRC/work/master/tls/biosphere/ssl/ca.pem --ssl-cert ~/SRC/work/master/tls/biosphere/ssl/client.crt --ssl-key ~/SRC/work/master/tls/biosphere/ssl/client.key  --ssl-verify kv read /nats/endpoint
--ssl-key must be provided in order to use certificates for authentication

        if c.sslCert != "" {
            if c.sslKey != "" {
                return nil, errors.New("--ssl-key must be provided in order to use certificates for authentication")
            }
            clientCert, err := tls.LoadX509KeyPair(c.sslCert, c.sslKey)
            if err != nil {
                return nil, err
            }

            tlsConfig.Certificates = []tls.Certificate{clientCert}
            tlsConfig.BuildNameToCertificate()
        }

However flipping the if c.sslKey logic still doesn't work.
