Primarily this involved removing the release namespace, which is
controlled by helm. If you want resources in a namespace you set
--namespace= with helm install, anything else leaves helm unable
to properly manage the resources.
I think the functions namespace won't work either on a delete.
Remove our non-standard namespace variable and use .Release.Namespace
to put fission deployments and services into.
(We still need the functionNamespace parameter, to customize what
namespace fission puts functions into.)
