[Python] Add Table.drop method for removing columns

[asfimport]

See ARROW-1374 for a use case. This function should take as an input a list of columns and return a new Table instance without them.

A well-defined interface for this implementation can be found in Pandas: https://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.drop.html

Uwe Korn / @xhochy:
We already have Table.remove_column. Shouldn't that already suffice?

[asfimport]

Wes McKinney / @wesm:
That removes a single column. It might be nice to have a convenience function that accepts a list of integers or a list of field names to drop, like pandas

Removed from 0.7.0 as non-urgent
