Adds other versions of Whereabouts

Added support for versions 0.5.4 and 0.6.1. Added rockcraft.yaml
files based on their Dockerfiles.

Adds /host folder in the rocks. The /install-cni.sh script requires
this folder. It does mkdir it, but the bitnami helm chart creates
the daemonsets with read-only filesystem, making it impossible to
create the folder.
