Fix ova auto-import issue for multi-datacenter environments

[abhinavmpandey08]

CLI fails with vSphere Provider setup is valid error on template deployment: please specify a datacenter error if a user doesn't specify a template name in the cluster config and the cli tries to autoimport the image. This only happens in multi-datacenter vSphere environments because it can't resolve to a default location to import images to.

We will need to provide a datacenter during import, most likely here:

eks-anywhere/pkg/providers/vsphere/internal/templates/factory.go

Line 59 in 99a4cdc

if err = f.createTemplate(ctx, machineConfig.Spec.Template, ovaURL, string(osFamily)); err != nil {

This is the original issue for reference: #409
