Description

This is a clone of issue ~~OCPBUGS-10728~~. The following is the description of the original issue:
—
Solution:

PR posted at https://github.com/openshift/installer/pull/7018

The summary of findings is that timeseries returned by
serviceruntime.googleapis.com/quota/allocation/usage can return other project_ids than intended.

With the filters added in the PR, only usages in the intended project will be used to match with limits of the same project.

Previously, it is possible to by chance have limits from intended project, and usage from an incorrect project accessible by the account that can lead to incorrect quota calculation (including potentially negative quota) that prevents an otherwise capable account from launching a cluster.

------

Description of problem:

error(MissingQuota): compute.googleapis.com/networks is not available in global because the required number of resources (1) is more than remaining quota of -negativenumber

During debugging of installer master branch, it is possible for quota calculated for networks service to be negative.
Watching the response, it is shown that the limits and the usage are coming from different projects in the account. If limits/usage were from the account it, the calculation would not have been negative.

LimitFromAccountWithLowerLimit - UsageFromAccountWithBiggerLimits = negativeQuota

The response for compute.googleapis.com/networks that is used for usage when inspected are from a different google cloud project than what is selected and used for limits.
https://github.com/openshift/installer/blob/9b44e67f7a5afb953712a12bc753cbb8fc12c9a4/pkg/quota/gcp/usage.go#L35

The timeseries' label project_id show value "openshift-gce-devel-ci" that is different than what was selected "openshift-gce-devel" for use during installation. See debug screenshots.

Version-Release number of selected component (if applicable):

[installer from source(master) 7667b46 |https://github.com/openshift/installer/commit/7667b46bd13a6091d8dd7791e77235adfa161935]

release architecture amd64

The same issue also occurred on 4.12.z release of the installer, meaning it's not a new regression.

How reproducible:

Once I got it to do once, it can repeatably be reproduced by reusing the same command. However, since I have to get stuff done, I try to get out of it by choosing a different --dir and/or cluster name which would sometimes work to get me out of it.

Steps to Reproduce:

(I can't actually verify but this is the last three things I did when this occured.)

1. openshift-install create cluster --dir clusters/gcp-dev1 --log-level=debug

FATAL failed to fetch Terraform Variables: failed to fetch dependency of "Terraform Variables": failed to generate asset "Platform Provisioning Check": metadata.name: Invalid value: "tkaovila": record api.tkaovila.gcp.devcluster.openshift.com. already exists in DNS Zone (openshift-gce-devel/devcluster) and might be in use by another cluster, please remove it to continue 

2. openshift-install destroy cluster --dir clusters/gcp-dev1 --log-level=debug

INFO Time elapsed: 27s                            
INFO Uninstallation complete! 

3. openshift-install create cluster --dir clusters/gcp-dev00 --log-level=debug

FATAL failed to fetch Cluster: failed to fetch dependency of "Cluster": failed to generate asset "Platform Quota Check": error(MissingQuota): compute.googleapis.com/networks is not available in global because the required number of resources (1) is more than remaining quota of -143

Actual results:

FATAL failed to fetch Cluster: failed to fetch dependency of "Cluster": failed to generate asset "Platform Quota Check": error(MissingQuota): compute.googleapis.com/networks is not available in global because the required number of resources (1) is more than remaining quota of -143
