Github Action: When a user creates a new namespace, ensure they have entered valid details

[jaskaransarkaria]

Background

When a user raises a PR for a new namespace in the cloud-platform-environments repo, we require the user to enter some details under annotations which we use to contact the user in the event of an issue. Currently, we have no check on these values, so a user may enter values which are not accurate.

Create a github action to lookup the value and ensure it is a valid entry for the following annotations:

cloud-platform.justice.gov.uk/source-code
cloud-platform.justice.gov.uk/team-name

Approach

• Read the changed files
• If it is a namespace, read the values of the above annotations
• look up the repo and check that it is public and accessible
• check the team name exists in the ministry of justice org

If either of the annotations do not meet the criteria then fail the action with a useful error message.

Consider how we should manage namespaces that exist already but contain invalid values for these annotations.
