Implement global.deployment.annotations in all GitLab owned sub-charts

Summary

Introduced by !893 (closed) as a peer to global.service.annotations, global.deployment.annotations serves to function as a means to produce annotations to all GitLab created charts as a part of the CNG. We should ensure this newly added functionality is included through out all the GitLab owned charts.
