/**
 * This test checks the upgrade path for mixed mode ssl + x509 auth
 * from disabled/keyfiles up to preferSSL/x509
 *
 * NOTE: This test is similar to upgrade_to_x509_ssl_nossl.js in the
 * sslSpecial test suite. This test uses ssl communication
 * and therefore cannot test modes that do not allow ssl.
 *
 * This test requires users to persist across a restart.
