Thanks for the pull. One feature that Phoenix (and other RDBMS) has is that
if a column identifier is double quoted, then it's treated as case sensitive.
Otherwise, it's upper cased as you've mentioned. Would be good if we could
accommodate this too in the phoenix-spark integration. If we can't do this,
then we may need to keep it as case sensitive as otherwise we can't support the
case sensitive use case.
> phoenix-spark should automatically convert DataFrame field names to all caps

> phoenix-spark will fail to save a DF into a Phoenix table if the DataFrame's
> fields are not all capitalized. Since Phoenix internally capitalizes all
> column names, the DataFrame.save method should automatically capitalize DF
> field names as a convenience to the end user.
