fix(generation): fix the volume var/path name

Underscores are forbidden by Kubernetes (should be a valid URL string),
we replace "_" by "-" in names, and we leave the values file using the
original name. So a volume named "foo_bar" in compose file, is
registered as "foo_bar" in the values file, but "foo-bar" is used as
volume name in deployments, volume claims, ...
