In kind, when we bind-mount a host directory it is first mounted into the kind container at /mnt, then into the pod at the desired location.
We accidentally picked this up for full-blown k8s, and were creating volumes at /mnt. This changes the behavior for both kind and regular k8s so that bind mounts are only allowed if a fully-qualified path is specified. If no path is specified at all, a default storageClass is assumed to be present, and the volume managed by a provisioner.
Eg, for kind, the default provisioner is: https://github.com/rancher/local-path-provisioner
```
stack: test
deploy-to: k8s-kind
config:
test-variable-1: test-value-1
network:
ports:
test:
- '80'
volumes:
# this will be bind-mounted to a host-path
test-data-bind: /srv/data
# this will be managed by the k8s node
test-data-auto:
configmaps:
test-config: ./configmap/test-config
```
