This allows standard OTLP env vars to be used for configuring tracing exporters. Note: This does mean that, as written now, if no env var is set the trace exporter will try to connect to the default OTLP address (`localhost:4318`). I've left this alone for now, but we could detect the OTLP vars ourselves and if not set don't configure the exporter. Signed-off-by: Brian Goff <cpuguy83@gmail.com>
