module: gcp_compute_health_check
description:
- Health Checks determine whether instances are responsive and able to do work.
- They are an important part of a comprehensive load balancing configuration, as they
  enable monitoring instances behind load balancers.
- Health Checks poll instances at a specified interval. Instances that do not respond
  successfully to some number of probes in a row are marked as unhealthy. No new connections
  are sent to unhealthy instances, though existing connections will continue. The
  health check will continue to poll unhealthy instances. If an instance later responds
  successfully to some number of consecutive probes, it is marked healthy again and
  can receive new connections.
