Drop Cinc EOL warning

What does this MR do?

Previously users would see this warning at the end of a reconfigure:

WARN: This release of Cinc Client became end of life (EOL) on May 1st 2024

This warning started to show up on a May 1, 2024, but the admin has no control over what version of Cinc is used. Disable this warning since it doesn't provide any useful information.
