This commit cleans up the google_compute_firewall resource to the Go
1.5+ style of not requiring map values to declare their type if they can
be inferred.
As part of Terraform 0.7.1 it was observed in issue #8345 that the state
migration for google_compute_firewall did not appear to be running,
causing a panic when an uninitialized member was read. This commit hooks
up the state migration function (which _was_ independently unit tested
but was not actually in place).
There is currently no good test framework for this, I will address this
issue in a future RFC.
Creating most google cloud resources uses the compute_operation to
wait for the creation to complete. However, the computeOperationWait*
functions always uses the global `config.Project`, instead of the resource-
specific one.
This means that creating resource in a project other than the main one
fails with a 404 on the operation resource.
This patch uses the project from google_compute_instance instead of the
global one.
This is the first step in removing the config dependency on "project".
This change is backwards-compatible because the value for this new
attribute defaults to the value from the provider.
