Add option to use SSH communicator for Windows

Code of Conduct

Description

Since Windows Server 2019/Windows 10 (build 1809), OpenSSH server has been available as a Windows feature. Packer supports using the SSH communicator for Windows so it would be nice if that option was made available.

Use Case(s)

• Secure remote management easier to set up (no "complicated" WinRM HTTPS).
• SSH as an option for Ansible, albeit "experimental" per the Ansible docs.
• Would make the communicator_proxy_* variables usable for Windows if SSH is used.

Potential Configuration

Introduce communicator_windows variable which can be set to either "winrm" or "ssh".

Modify autounattend.xml to use different init script depending on communicator_windows.

Example SSH config in init script:

# Install OpenSSH
Write-Output 'Installing the OpenSSH client...'
Add-WindowsCapability -Online -Name 'OpenSSH.Client~~~~0.0.1.0'

Write-Output 'Installing the OpenSSH server...'
Add-WindowsCapability -Online -Name 'OpenSSH.Server~~~~0.0.1.0'

# Configure OpenSSH server
Write-Output 'Starting OpenSSH server...'
Start-Service sshd

Write-Output 'Setting OpenSSH server to start automatically...'
Set-Service -Name sshd -StartupType 'Automatic'

# Allow OpenSSH Server in the Windows Firewall
Write-Output 'Allowing OpenSSH server in the Windows Firewall...'
netsh advfirewall firewall set rule group="OpenSSH Server" new enable=yes
netsh advfirewall firewall set rule name="OpenSSH SSH Server (sshd)" new enable=yes action=allow
