Deprecate the ansible provision playbook

[afbjorklund]

Currently we have an "ansible" type of provision, that runs a playbook from an inventory.

• Additional provisioning formats beyond shell scripts #2282

It would be better for the user to run these outside of Lima, after the instance is started.

ansible-playbook -i inventory.yaml playbook.yaml

If really wanting to use Ansible for VM provisioning, one could start it from a shell script?

That is, install ansible on the instance and then run the playbook from a data file.

Generating an inventory is not needed when run locally, with ansible_connection=local

It is only used when ansible is running on the host, to supply the hosts and groups.
