Add integration test provider for vmware (#55772)

* Add integration test provider for vmware

This change adds a new remote cloud provider option for vmware,
supporting dynamic environments running on worldstream.nl as well as
static environments specific by the user in a cloud-config template.

+# This is the configuration template for ansible-test VMware integration tests.
