Added job entry points for iterated smoother and analysis_select_module
Added analysis_config function to get the name of the currently selected analysis module
Added checks in the high level run routines that the iterable status of the module is sound
Added (fatal) check in enkf_main_UPADTE() that we are not using an iterable module with multi step update
