Should PeriodicExportingMetricReader call forceFlush on shutdown?

[danielgblanco]

More context on open-telemetry/opentelemetry-specification#2983

Although the OpenTelemetry Specification does not state it (see issue above), other language SDKs (e.g. Python or Java) perform the effects of a forceFlush as part of the call to shutdown. In opentelemetry-js, the MeterProvider.shutdown() has a comment indicating that a call to shutdown will flush all buffered data, but the implementation of the PeriodicExportingMetricReader.shutdown() does not.

I'd like to discuss if Node should follow the same implementation, or if maintainers of this repo have any opinions on the opentelemetry-specification issue above. Thanks.

• This only affects the JavaScript OpenTelemetry library
• This may affect other libraries, but I would like to get opinions here first
