MDL-38541 Make sure course cache is cleared properly during upgrade
- Core upgrade MUST NOT call rebuild_course_cache() at all - update DB directly instead
- Plugins MUST call rebuild_course_cache(.., TRUE) for clearing the course cache and can not update DB directly
- Plugins MUST NOT call rebuild_course_cache() unless for clearing the cache
- Created function upgrade_ensure_not_running() to be included in other functions that can not be used during upgrade
