DL: Add a helper function to load custom top n accuracy functions

JIRA: MADLIB-1452

This commit enables the top_n_accuracy metric. The current parser
cannot use top_n_accuracy(k=3) format because we don't want to
run eval for security reasons. Instead, we add a helper function
so that the user can easily create a custom top_n_accuracy
function.
