/**
 * This test checks the upgrade path from noauth/allowTLS to x509/requireTLS
 *
 * NOTE: This test is similar to upgrade_noauth_to_x509_ssl.js in the ssl test
 * suite. This test cannot use ssl communication and therefore cannot test
 * modes that only allow ssl.
 *
 * This test requires data to persist across a restart.
 * @tags: [requires_persistence]
