[2/4] struts git commit: Make it easier to extend to override interceptor stack

Make it easier to extend to override interceptor stack

Just as createAction is split out from init, it would be great to split out creating the interceptor iterator creation so it can be overridden without having to override all of init().  (Needed this to always prepend an i18n interceptor to all stacks).
