Add monitoring_notification_channel resource support to terraform-validator.

[ankurdua]

Added google_monitoring_notofocation_channel entry to resource_converters.go.erb for adding support in tfv.

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.

@ScottSuarez do you want to take a stab at reviewing this one?

Closing for now - see comment on TFV PR.

[melinath]

Reopening - after some discussion the risk seems low enough that adding assets like this should be fine.
