Add the `vmware/scenario/vcenter_only` alias to be able to identify the
vmware test roles that can be tested with just on vcenter instance.
Also, add a check to be sure we don't try to attach ESXi hosts if none
has been defined.
- In order to keep the integration with `ansible-test`, we prefer to avoid any
interaction with the Ansible inventory file.
- split up the prepare_vmware_tests/defaults/main.yml in two
configuration files: one for vcsim and one for a real environment
- remove all the access to hostvars
- directly interact with the ESXi to mount/umount the datastore

- record the virtual machine folder in the environment configuration
- vmware_guest_move: Use https://github.com/ansible/ansible/pull/55237
