Make the stdout exporter a package (open-telemetry#963)

* Make the stdout exporter its own package Follow the pattern of the other exporters. * Update dependabot with stdout exporter * Add replace directives for stdout exporter * Remove outdated example test from metric SDK * go mod tidy * Update othttp example test Remove unused stdout exporter. * Remove tests in API that depend on stdout exporter The global package does not need to be validated with the SDK. A more properly constructed end-to-end integration test should be built if this is actually needed. * Add replace clause for otel in stdout go.mod
