Since the server now executes the statements previously executed by mysql_upgrade, the client is now deprecated, and returns the value 2, meaning that the server is already upgraded. The intention of returning a value != 0 was to make users aware of the deprecation. However, there are indications that this results in undesirable breakage of toolchains, and hence, we change the client to return 0 unconditionally.

How to repeat:
Run the mysql_upgrade client from 8.0.16, check its return value.

Suggested fix:
Change return value from 2 to 0.
