Long cluster names are trimmed by the installer. Warn the user before this happens because if the user intended to distinguish these based on some suffix at the end of a long name, the suffix will get chopped off. If some resources are created on the basis of cluster name alone (rare), there could even be conflicts.

    1. Use a "long cluster name" (at the moment > 27 characters)
    2. Deploy a cluster
    3. Look at the names of resources, the name will have been trimmed.
    

Cluster resources with trimmed names are created.

The same as Actual results, but a warning should be shown.
