I know it sounds like lunacy but there are non-standard AWS regions in which Kubernetes might be deployed (e.g. Eucalyptus). Instead of enumerating each zone in pkg/credentialprovider/aws/aws_credentials.go, perhaps it would be appropriate to add a flag in a configuration file to disable the check.

The region validation would be enabled by default, handling the vast majority of cases. In the edge case that region validation is undesirable, this flag would provide a workaround.

I'd like to work on the solution. If you'd like to assign this to me, that's just fine.

AWS: Added experimental option to skip zone check

This pull request resolves #28380.  In the vast majority of cases, it is appropriate to validate the AWS region against a known set of regions.  However, there is the edge case where this is undesirable as Kubernetes may be deployed in an AWS-like environment where the region is not one of the known regions.

By adding the optional **DisableStrictZoneCheck true** to the **[Global]** section in the aws.conf file (e.g. /etc/aws/aws.conf) one can bypass the ragion validation.
