Add map and array attribute value type support (#1656)
Browse files Browse the repository at this point in the history 
Map and array attribute value types which were recently added to the specification had not been implemented in the collector yet. This PR implements across all tracing receivers and exporters.

**Link to tracking Issue:** #1590

**Testing:** Added map and array attribute values to golden dataset. All unit and correctness tests continue to pass.
