google-cloud: Remove deprecated automatic_restart field

* In terraform-provider-google v0.1.3, it is no longer neccessary
to supply a (duplicated) value for the instance_template field
automatic_restart
* Previously this field was set to match the scheduling
automatic_restart since the field defaulted to true and would
cause plan to always show changes were needed
