L3 default support for Network Load Balancer

[drebes]

If this PR is for Terraform, I acknowledge that I have:

• Searched through the issue tracker for an open issue that this either resolves or contributes to, commented on it to claim it, and written "fixes {url}" or "part of {url}" in this PR description. If there were no relevant open issues, I opened one and commented that I would like to work on it (not necessary for very small changes).
• Generated Terraform, and ran make test and make lint to ensure it passes unit and linter tests.
• Ensured that all new fields I added that can be set by a user appear in at least one example (for generated resources) or third_party test (for handwritten resources or update tests).
• Ran relevant acceptance tests (If the acceptance tests do not yet pass or you are unable to run them, please let your reviewer know).
• Read the Release Notes Guide before writing my release note below.

Release Note Template for Downstream PRs (will be copied)

compute: added support for `L3_DEFAULT` as `ip_protocol` for `google_compute_forwarding_rule` and `UNSPECIFIED` as `protocol` for `google_compute_region_backend_service` to support network load balancers that forward all protocols and ports.

One small question, running VCR to get test results otherwise

Code LGTM (ignore the VCR failure, I superseded it w/ a manual run)

Not sure what's up w/ the test failure, iam.go didn't import sort for no good reason. Ignoring that.
