Function flatten_node

src/records/RecYAMLDecoder.cc:203–221

@brief Iterate over a node and build up the field name from it. This function walks down a YAML node till it find a scalar type while building the record name, so if a node is something like this: diags: debug: enabled: 0 this function will build up the record name "diags.debug.enabled" and then it prepend the "proxy.config" to each name, this will be the record name already known by ATS. Ever

/// @param handler Scalar node function handler, called every time a scalar type is found.
/// @param errata Holds the errors detected.
