Issue Overview

Related to: Issue #21190 (closed)

Description:

Currently, there is no functionality to deploy pods of different services to specific zones within our infrastructure. This feature would be beneficial for troubleshooting purposes and would provide additional flexibility for customers who want to decide where to schedule pods.

Currently this feature has only been implemented for registry , for reference gitlab-org/charts/gitlab!3669 (merged) , changes to other charts should be pretty similar

Might potentially also help with cells deployment in the future

Tasks

• Figure out how many charts can we deploy this functionality to
• The effort it would take
