* Temporarily opt-out export.Labels from label encoding stuff * Stop passing label encoding stuff to export.Labels * Drop label encoding stuff from SDK * Dogstatd exporter does not need to implement label exporter anymore * more dogstatd exporter fixes * export labels get back to encoding stuff in a lame way, but improvements are coming in following commits * Get encoded labels through export.Labels * make SDK to provide its own implementation of export.Labels * drop dead code * add noop label exporter * make export simple labels immutable * Move the default label encoder to export package * Simplify the simple export labels a bit * Reserve some label exporter IDs * Document and shuffle the code a bit * Prepare for bring the iterator benchmark test back We can install a callback to the Batcher's process function - this is the place where we can access the labels, and thus test the label iterator. * Bring back the iterator benchmarks * Simplifications and docs * Fix copyright to be consistent with the rest * Fix typo * Put reserved label encoder IDs into constants We get fewer comments about magic numbers that way. * Fix the label encoder as label exporter thinko
