Describe

• Refine caches of converting function.

For the function with same detent source code, only once convert into ast nodes once and cache them. For two function with same dedent code, the second function will reuse the transformed ast node and save a new tmp file and reload a independent module because they can hold difference global variables in their located files.

• clean useless code related with feed_name_id
