Consolidate and improve reset_index

[isVoid]

Partial of #9038

This is a rewrite of reset_index to share some common logics between Series and DataFrame. It extends it's capability to handle level argument for multi-level index, col_level and col_fill for multi-level column name support. And adds name argument support for series api.

@isVoid at a glance, my best guess for why tests are failing now is this change on 5b81aa3. Specifically, the new _index_from_columns function is using len(columns) to determine the keys, but in this case that isn't quite right because you only want to use the first n_index_columns columns. If that's right, maybe just calling _index_from_columns(columns[:n_index_columns]) would fix it.
