Environment Specs so far had only an image URL to specify a container image. This was fine for public images but fell short in a few of cases: (a) Using private image registries (b) Specifying environment variables (this is needed for workflows helm install) (c) Setting a SecurityContext for the container This change adds the Container object to both build and runtime Environments. Compatibility is preserved -- the existing ImageURL field is still used. See the comments in types.go for the overriding rules in the case that both Container and ImageURL are specified.
