Enabling the maxTimeAlwaysTimeOut fail point will cause any query or command run with a valid non-zero max time to fail immediately. Any getmore operation on a cursor already created with a valid non-zero max time will also fail immediately.

Original below:

Please add a server fail point that will make the next command or query time out, so that we can run a command that says, "I'm going to test MaxTimeMS, please time out the next thing I do with appropriate error." for ease of testing drivers.
