Run Communicator Prepare function during config

[lomeroe]

What this PR does / why we need it: Runs the Communicatore "Prepare" function during config. This function provides additional setup for the communicatore, for example, allowing auth via NTLM (i.e. the winrm_use_ntlm config parameter does not have an effect w/o running the Prepare function).

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
Fixes #

How Has This Been Tested?: Windows images created with/without winrm_use_ntlm boolean set.

Special notes for your reviewer:

Please confirm that if this PR changes any image versions, then that's the sole change this PR makes.

Release note:

[wolfganghuse]

Hello @lomeroe I would like to work on your PR and add it to our next release... can you provide some more details how to test that switch ? Any prerequirements on the Windows-Deployment, needs NTLM be enabled through autounattend.xml ?
EDIT: Nevermind... managed to test it in my env by removing basic-auth from unattended.xml

[lomeroe]

basically, all that is needed is to ensure the winrm auth config has Basic set to false (which should be the default), and NTLM will be tried instead of cleartext/basic authentication

c:\windows\system32\winrm.cmd winrm/config/service/auth @{Basic="false"}

[wolfganghuse]

Yes, that worked for my test… do you also experience problems (HTTP401) when using NTLM on Windows 2022?

[lomeroe]

No, both 2019 and 2022 worked form me.
