Ansible provisioner do not work with ISPW and MACVM

[sfc-gh-banowak]

Overview of the Issue

Ansible is unable to work with parallels-macvm

Reproduction Steps

1. Create a simple MacOS VM inside parallels and make sure that ssh auth with password works. Sonoma was used as VM version
2. Create a packer configuration where you are using Ansible
3. Provide for builder ssh_username and ssh_password parameters for macvm builder.
4. Since those two were passed no ssh key is generated.

[ssh_keypair_name](https://developer.hashicorp.com/packer/docs/communicators/ssh#ssh_keypair_name) (string) - If specified, this is the key that will be used for SSH with the machine. The key must match a key pair name loaded up into the remote. By default, this is blank, and Packer will generate a temporary keypair unless [ssh_password](https://developer.hashicorp.com/packer/docs/communicators/ssh#ssh_password) is used. [ssh_private_key_file](https://developer.hashicorp.com/packer/docs/communicators/ssh#ssh_private_key_file) or [ssh_agent_auth](https://developer.hashicorp.com/packer/docs/communicators/ssh#ssh_agent_auth) must be specified when [ssh_keypair_name](https://developer.hashicorp.com/packer/docs/communicators/ssh#ssh_keypair_name) is utilized.

5. Try to run the Ansible provisioner without proxy.
6. Read the msg:

    parallels-macvm.macvm_automated: Not using Proxy adapter for Ansible run:
    parallels-macvm.macvm_automated:    Using ssh keys from Packer communicator...

7. Watch as Ansible is trying to get the SSH key, which is not generated because the password is passed.

==> parallels-macvm.macvm_automated: Executing Ansible: ansible-playbook -e packer_build_name="macvm_automated" -e packer_builder_type=parallels-macvm -e packer_http_addr=0.0.0.0:0 --ssh-extra-args '-o IdentitiesOnly=yes' -vvvv -e ansible_ssh_private_key_file=/var/folders/s4/mcd4dxfn0vz_ssgbz0xnj4xw0000gn/T/ansible-key2040784890 -i /var/folders/s4/mcd4dxfn0vz_ssgbz0xnj4xw0000gn/T/packer-provisioner-ansible1035096009 /Users/banowak/Work/jenkins-macos-ami/images/aws/ansible/main.playbook.yml

8. Since Ansible requires using SSH keys, which are not generated (empty), observe a connection denial due to an invalid key.
   Log without user passed to ansible:

Log Fragments and crash.log files

Possible workarounds

I will try not to shut down the machine and connect to it with a null provisioner.
