to pandas index metadata

I'm going to be AFK for about 5 or 6 hours, @cpcloud or @xhochy please go
and ahead and merge this once the Python builds run in Travis CI so
@jorisvandenbossche can rebase. I'll be back on later today to work on some
other patches for 0.8.0

> Project: Apache Arrow

> https://github.com/pandas-dev/pandas/pull/18201
> In short we need a way to map index column names to field names in an arrow
> Table.
> Additionally, we're depending on the index columns being written at the end
> of the table and fixing this would allow us to read metadata written by other
> systems (e.g., fastparquet) that don't make this assumption.
