* Consolidate stdout exporter * Move config to own file and match project standard * Abstract Exporter into unified struct * Rename trace part of the exporter * Update import paths and configuration * Update tests * Update InstallNewPipeline to not return traceProvider It is a registered global, access it that way. * Update example_test * Update docs * Update example to be for whole package * Update metric output Closer match the span output. * Clean up span output Print as a batch and cleanup marshaling. * Correct spelling error in doc * Add Exporters README * Update Changelog * Propagate changes to rest of project * Lint fixes * Fix example test in metric SDK * Add disable config options for trace and metric Co-authored-by: Liz Fong-Jones <lizf@honeycomb.io>
