Description of problem:

Ability for OpenShift Gitops to handle larger gitops repos

Prerequisites (if any, like setup, operators/versions):

GitOps 1.11.1

Actual results:

Fails due to out of disk space

Expected results:

Deploys helm charts successfully

Additional info (Such as Logs, Screenshots, etc):

The ArgoCD HA guidelines [1] says:
> argocd-repo-server clones the repository into /tmp (or the path specified in the TMPDIR env variable). The Pod might run out of disk space if it has too many repositories or if the repositories have a lot of files. To avoid this problem mount a persistent volume.

However the Gitops/ArgoCD operator doesn't support setting this [2]. This means we're unable to use large git repos with OpenShift Gitops currently.
