To enable users to migrate from Gitaly to Praefect, we need to allow
both configurations to run in parallel.

Currently, the spec for the Gitaly StatefulSet is split out into a
common file that either the Praefect or the non-Praefect StatefulSet can
reference. However, since we need both running at the same time,
checking if .Values.global.praefect.enabled=true will cause errors in
the non-Praefect statefulset.

We may be able to merge portions of this later, but for now it is more
straightforward to separate the configurations so both can be deployed
at the same time.
