feat: Allow Fields Specification and Capture Nearest Fields

[metal-messiah]

Adds configuration to specify what fields to capture from target elements. This change extends that behavior to also search up the parent tree for the "nearest" matching field when not present on the target.

Overview

This was spawned from feedback and POC tied to internal NR1 use cases and product analytics. Exposing to customer base to benefit all.
