Helm: Missing `emptyDir` mount in querier StatefulSet in HA mode

[bastjan]

Helm release v1.4.0 moved the Querier from a Deployment to a StatefulSet.

The old deployment mounted an empty dir to /parseable/staging:

parseable/helm/templates/querier-deployment.yaml

Lines 70 to 71 in 245aa8b

	- name: stage-volume
	emptyDir: {}

This was removed from the new STS and thus on systems with readOnlyRootFilesystem set, the querier crashes on startup with a rather obscure error message:

Error: IO Error: Permission denied (os error 13)

Caused by:
Permission denied (os error 13)

Affected versions

Helm release v1.4.0
