Consider removing VOLUMES from kapacitor Dockerfile

Our use case does not require persisting the Kapacitor bolt DB outside the container. Our security requirements also require running the container as a non-root UID/GID. The VOLUMES declaration in the Dockerfile causes a volume mount owned by root which requires further workarounds.
If your image omits VOLUMES, then the image should be more flexible for downstream users.

Locate the Kapacitor Dockerfile and inspect its VOLUMES declaration. Remove that declaration and verify that the resulting image does not force a root-owned volume mount, while remaining usable for downstream users that need their own persistence setup.
