GoogleCompute Builder does not work with "source_image_family" key

[adarobin]

packerlicious version

0.8.0

Expected behavior

I expected to be able to use the source_image_family option in place of the source_image option. Per the documentation, at least one or the other is required.

Actual behavior

ValueError: Resource source_image required in type googlecompute

Steps to reproduce

template = Template()
gcp_builder = builder.GoogleCompute(
account_file = "{{user `gcp_account_file`}}",
project_id = "{{user `gcp_project_id`}}",
zone = "{{user `gcp_zone`}}",
source_image_family = "ubuntu-1804-lts",
disk_size = 10,
disk_type = "pd-ssd",
machine_type = "n1-standard-2",
image_name = "test-ubuntu-1804-bionic-v{{isotime \"20060102\"}}",
image_family = "test-ubuntu-1804-lts",
communicator = "ssh"
)
template.add_builder(gcp_builder)
print template.to_json()
