Switch to StatefulSet resources for stateful components (#8985)

### What problem does this PR solve?

Switch to Kubernetes StatefulSet resources for MySQL, Minio and vector
DB since these are stateful application components. This makes
operations such as helm upgrade smoother since the default container
update strategy becomes a sequential rolling update of each pod.

Also fixes a bug in the name template for the Minio stateful set
resource to align it with the naming convention used for other
components.
