OTLP exporter options separate out MetricReader options (#2717)

* Separate out OtlpMetricReaderOptions from OtlpExporterOptions * Collapse config delegates into one * Rename AggregationTemporality to Temporatlity * Update public API * Change parameter names * Move MetricReaderOptions to SDK * Default OTLP metric exporter to use a periodic metric reader and cumulative temporality * Update example to configure exporter options * Update public API * Everyone loves a good stackoverflow * Update public API * Fix bad merge * Change namespace * Fix the public API * I ❤️ trying to get the public API correct without Visual Studio * Remove check for unspecified temporality Co-authored-by: Cijo Thomas <[email protected]>
