Add a new file to record the variables that are shared with the two
scenarios (real_lab and vcsim).
The goal is to reduce the the amount of boilerplate configuration from
a user perspective.
- 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
