 * Tests simultaneous upgrade from noauth/no-ssl to x509/requireSSL on a sharded cluster.
 * The purpose is to verify the connectivity between mongos, config server, and the shards

 * NOTE: This test is similar to the mixed_mode_sharded_transition.js in the ssl
 * test suite. This suite does not use ssl so it cannot test modes with ssl.
