feat: Add a new resource for cluster personality (ESXi image)

[spacegospod]

Summary of Pull Request

This PR introduces a new resource for configuring cluster personalities https://developer.vmware.com/apis/vcf/latest/personalities/

For now I am only including support for clusters that reside in VCF-managed vCenters. The exporting of images based on clusters from external vCenters requires additional automation in the provider for vSphere and can be added if demand arises.
