Backend service support for internet NEG backend

[slevenick]

Fixes: hashicorp/terraform-provider-google#6155

Similar to #3764 but with virtual field to strip max_utilization from request body. This allows users of the regular backend service to send max_utilization = 0.0, but will show max_utilization in initial create diff of a backend with a network endpoint

Add ability to set global network endpoint group as backend for backend service. Make health_checks optional if NEG is used. Virtual field added to enable this

Release Note Template for Downstream PRs (will be copied)

compute: Added support to `google_compute_backend_service` for setting a network endpoint group as `backend.group`

LGTM, just a quick docs change. Can you also update the title of this PR to reflect the new approach, and update the changelog to not have backticks around compute?
