[Metricbeat] GoogleCloud Dashboards using wrong fields

[LucaWintergerst]

The GoogleCloud Dashboards are using field names like googlecloud.compute.instance.cpu.utilization, while Metricbeat is sending fields like googlecloud.compute.instance.cpu.utilization.value. Note the .value at the end. This causes all visualizations to break.

For confirmed bugs, please report:

• Version: 7.8.0-0dba676b
• Operating System: MacOs

• Steps to Reproduce:

Setup Metricbeat with the GoogleCloud module

- module: googlecloud
  metricsets:
    - compute
  region: "us-central1"
  project_id: "elastic-foobar"
  credentials_file_path: "foobar.json"
  exclude_labels: false
  period: 1m

setup Dashboards ./metricbeat setup --dashboards
start Metricbeat ./metricbeat -e
try to load Dashboard
Kibana will error with Error fetching fields for index pattern metricbeat-*
