Validate PKE AWS cluster name length to make NLB too long name failure a pre-operation error

[pregnor]

Is your feature request related to a problem? Please describe.

Currently the PKE AWS cluster creation with names longer than 24 characters fails due to the NLB name cannot exceed the length of 32 characters and the Pipeline generated name takes up 8 characters.

This is only revealed once the cluster creation failed fatally.

Describe the solution you'd like to see

Cluster creation request validation should intercept these cases and return a validation error as long as this limitation is in place.

Describe alternatives you've considered
