As discussed in HELP-22228, <=3.2 servers used to return the following state change error:

{ok: 0, code: 10058, errmsg: "not master"}

Error code 10058 is currently "unstable" but the drivers to would like to add it to our client-side list of state change error codes. We'd like the server to do the same to ensure that error code 10058 doesn't accidentally get reused for non-state change errors in the future.
