pfSense freebsd failing to deploy.

[pf-freebsd-setup]( https://github.com/Azure/azure-quickstart-templates/tree/master/pf-freebsd-setup )

### Issue Details
Template is failing to fully deploy. The last few steps (nat/configurepf.sh) are failing with the following error:

I do not know if it's relate, but because of this we are also unable to access the web gui of pfSense to configure it ourselves.

Start with the pf-freebsd-setup template and inspect the nat/configurepf.sh step and configurepf VM extension referenced in the deployment error. Reproduce the deployment failure and trace the malformed status file; done means the final deployment steps complete successfully and the pfSense web GUI is accessible.
