* WIP: add global API * WIP * Add a global meter. * moved global access out of metric because of loop imports * fix linting issues * remove changes from other lint failures. * Add changelog * Fixes for comments. Changed name of global API. Added stop to all race tests go routine. Added race tests for other instruments. * Apply suggestions from code review Co-authored-by: Tyler Yahn <MrAlias@users.noreply.github.com> * Consolidated instrument tests * fixed lint, and removed unneeded type checking * change require's to asserts. * Update misspelling Co-authored-by: Tyler Yahn <MrAlias@users.noreply.github.com> * Fix meter race test. * Copy SetTracerProvider logic. * Fix global test for panic. * Fix linting error * bump testify version * moved changelog into unreleased Co-authored-by: Aaron Clawson <MadVikingGod@users.noreply.github.com> Co-authored-by: Tyler Yahn <MrAlias@users.noreply.github.com>
