The driver fails the redaction test of isMaster/hello with speculativeAuthenticate. However, the Java driver doesn't generate events for commands executed as part of the connection handshake, so in practice I wouldn't expect actual applications to encounter it (speculativeAuthenticate is not even documented in the MongoDB manual).

When this bug is fixed, the "hello with speculative authenticate" unified command monitoring test should be un-skipped in the test runner.

In addition, we should ensure that logging of commands that should be redacted are also redacted.  Currently they are not.
