Next iteration of stable counterparts for SRE teams with Eng departments

The first iteration of stable counterparts assigned people. Now that we have three teams that will grow to approximately 8 each, we should discuss team alignments.

For the engineering sub-departments/product categories, the 4 bigger groups are:

1. Dev
2. CI/CD
3. Ops
4. Secure
5. Defend
6. Growth
7. Enablement

On another axis of team ownership, we need to have stable owners for:

1. Chef/Terraform (Infra as code and config mgmt general tooling)
2. Observability: Prometheus/Grafana - some overlap with Ops Dept, but worth its own infra focus
3. Observability: Logging - making sure all logging pipelines to Stackdriver and ELK are working correctly
4. Backups for Git data and postgres and verification of that tooling

For an outcome, we will look to create a blueprint and update the handbook section of [how we work] (https://about.gitlab.com/handbook/engineering/infrastructure/production/#workflow--how-we-work).
