reflect ci/cd releases in the gitops repository

[romaninsh]

New GitOps flow (see https://codefresh.io/features/gitops/) requires kubernetes yaml files to be versioned in a separate repository. We currently store that in "apps" folder - and reference some stable branch. CI/CD process uses "patch" when deploying new image from codefresh and argocd is configured to ignore change in image tag.

This is wrong use of GitOps instead it should follow the guide - release from ci/cd (e.g. new atk.ui demo) should commit new tag into the infrastructure repo (or some other repo), this should then be picked up by the cluster and sync into a new state.

Several things would need to be refactored for this.

This should address problem where application state reverts back to older version and would also allow us to ditch DO credentials in codefresh that has been expiring/failing periodically.
