This issue is to check that if units are manually hard coded in the provider map for GCP and GCP on Openshift, that those units are correct for the values we are returning.

Examples:
1. https://github.com/project-koku/koku/blob/main/koku/api/report/gcp/provider_map.py#L308
2. https://github.com/project-koku/koku/blob/main/koku/api/report/gcp/provider_map.py#L428
