Function to traverse dataframe schema.

Question

Function to traverse dataframe schema.

It would be nice to have a function which would traverse schema and apply some function on a column. For example, we could use it to make columns nullable or add metadata.

See the DataFramExt#setNullableForAllColumns method. Would be happy to add additional functions to add metadata as well, feel free to open a PR anytime!
