StackdriverStatsExporter.createAndRegister takes 10 seconds

Please answer these questions before submitting a bug report.

What version of OpenCensus are you using?

0.28.3

What JVM are you using (java -version)?

11.0.13

What did you do?

If possible, provide a recipe for reproducing the error.

The following line of code is taking 10 seconds to execute, and the document suggests running this on the main thread at startup. This delay is causing K8S to kill the pods before they startup.

StackdriverStatsExporter.createAndRegister(
                StackdriverStatsConfiguration.builder()
                    .setMetricNamePrefix("custom.googleapis.com/<redacted>/")
                    .build()
            )

In my case, sometimes it took 5 minutes.

    @EventListener(ApplicationPreparedEvent.class)
    private void initializeOpenCensusCore() {
            StackdriverStatsExporter.createAndRegister(StackdriverStatsConfiguration.builder()
                    .setExportInterval(Duration.fromMillis(EXPORT_INTERVAL))
                    .build());
...
