sync-rover-groups: request updater service accounts explicitly

[psalajova]

Every secret collection currently gets its own GCP updater service account, whether anything uses it or not. Each one costs two bindings in the openshift-ci-secrets project IAM policy, which GCP caps at roughly 67KB — at the ~115 collections the Vault migration will onboard, those bindings alone are about 63KB and put the policy over the cap. That is the remaining blocker for the migration.

So they become opt-in, and this names the three collections that actually have one in use:

telcov10n-ci:
  secret_collections:
  - telcov10n-ci
  updater_service_accounts:      # new
  - telcov10n-ci

test-platform-gsm-secrets-owners:
  secret_collections:
  - test-platform-infra
  - psalajova-first-secret
  updater_service_accounts:      # new
  - test-platform-infra
  - psalajova-first-secret

Documented for users in openshift/ci-docs#620.

Depends on openshift/ci-tools#5401

Walkthrough

The rover group configuration adds updater service accounts to telcov10n-ci and test-platform-gsm-secrets-owners.

Changes

Rover group configuration

Layer / File(s)	Summary
Configure updater service accounts core-services/sync-rover-groups/_config.yaml	Adds telcov10n-ci to its group and adds test-platform-infra and psalajova-first-secret to test-platform-gsm-secrets-owners as updater service accounts.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: ⚪ Minimal · up to 6f312

The configuration limits updater service-account assignments to the specified rover groups, reducing unnecessary IAM bindings. No concrete merge-blocking risk is identified.

my-team-secrets__updater-service-account secret so it reconciles with the stated
restriction that group members cannot read secret values. Explicitly identify
whether this secret is an exception or describe the actual mechanism by which
the updater key is accessed.

@psalajova: no rehearsable tests are affected by this change

Note: If this PR includes changes to step registry files (ci-operator/step-registry/) and you expected jobs to be found, try rebasing your PR onto the base branch. This helps pj-rehearse accurately detect changes when the base branch has moved forward.

Interacting with pj-rehearse

Comment: /pj-rehearse to run up to 5 rehearsals
Comment: /pj-rehearse skip to opt-out of rehearsals
Comment: /pj-rehearse {test-name}, with each test separated by a space, to run one or more specific rehearsals
Comment: /pj-rehearse more to run up to 10 rehearsals
Comment: /pj-rehearse max to run up to 25 rehearsals
Comment: /pj-rehearse auto-ack to run up to 5 rehearsals, and add the rehearsals-ack label on success
Comment: /pj-rehearse list to get an up-to-date list of affected jobs
Comment: /pj-rehearse abort to abort all active rehearsals
Comment: /pj-rehearse network-access-allowed to allow rehearsals of tests that have the restrict_network_access field set to false. This must be executed by an openshift org member who is not the PR author

Once you are satisfied with the results of the rehearsals, comment: /pj-rehearse ack to unblock merge. When the rehearsals-ack label is present on your PR, merge will no longer be blocked by rehearsals.
If you would like the rehearsals-ack label removed, comment: /pj-rehearse reject to re-block merging.
