Added tf_data_dir parameter and changed plugin to respect TF_DATA_DIR
This commit will enable the plugin to do parallel builds. The first change is to use Terraform's TF_DATA_DIR environment variable to change the state directory so they will not conflict each other in parallel executions The second change is to change the plan's output to a different file so they will not be overriden by another parallel execution
