Updates for Backstage

[ChrisLivettEH]

Summary

To better maintain our repositories, we are adding/updating CODEOWNER files and catalog-info.yaml to all repositories, where necessary. This will allow Backstage to detect all repositories and collate information to be used by our engineers.

Required actions

The catalog-info.yaml file contains only basic information and can be expanded to better improve the usage of Backstage. Recommended additions include:

• Adding circleci.com/project-slug in the annotations section to link to CircleCI (e.g. circleci.com/project-slug: github/Thinkei/react-signature-pad)
• Adding sonarqube.org/project-key in the annotations section to link to SonarQube (e.g. sonarqube.org/project-key: react-signature-pad)
• Adding datadoghq.com/dashboard-url in the annotations section to link to Datadog (e.g. datadoghq.com/dashboard-url: https://p.datadoghq.com/sb/abc-123-abc). Note: The dashboard must be set to have a publicly visible link for this to work, please use caution when doing this to avoid potentially disclosing any sensitive information. See Backstage Datadog Plugin for more information
• If this repository exposes an API, declare the API as seen in form service catalog-info.yaml, by adding a providesApis link in the spec, and then referencing the OpenAPI docs in the kind: API spec. Note: Backstage uses Swagger, which does not currently support OpenAPI 3.1, so either the docs need to be OpenAPI 3.0 or lower, or wait until OpenAPI 3.1 support is released later this year
