Speed up journey extract_parameterized_parts
Micro optimization: `reverse.drop_while` is slower than `reverse_each.drop_while`. This doesn't save any object allocations.
Second, `keys_to_keep` is typically a very small array. The operation `parameterized_parts.keys - keys_to_keep` actually allocates two arrays. It is quicker (I benchmarked) to iterate over each and check inclusion in array manually.
This change buys us 1774 fewer objects per request
