+* meant to be used by all components. This helper makes it easy to add those
+* values to a containers environment. No need to do any checks whether or not
+* they have to be added.
+*
+* This helper is suitable to be used with `env_:` from the Kubernetes Jsonnet
+* library. If the list form is used, combine it with `com.envList`.
+*
+* \return Dictionary. When configured, contains the http proxy environment
+*         variables in both upper and lower case form. Will be empty otherwise.
