ConfigurableMetricReaderProvider

```
public interface ConfigurableMetricReaderProvider
```
A service provider interface (SPI) for providing additional metric readers that can be used with the autoconfigured SDK. If the otel.metrics.exporter property contains a value equal to what is returned by getName(), the exporter returned by createMetricReader(ConfigProperties) will be enabled and added to the SDK.
Where as ConfigurableMetricExporterProvider provides push-based MetricExporters to be paired with PeriodicMetricReader, this SPI facilitates pull-based MetricReaders.
This class is internal and is hence not for public use. Its APIs are unstable and can change at any time.

Modifier and Type	Method	Description
`MetricReader`	`createMetricReader(ConfigProperties config)`	Returns a `MetricReader` that can be registered to OpenTelemetry by providing the property value specified by `getName()`.
`java.lang.String`	`getName()`	Returns the name of this reader, which can be specified with the `otel.metrics.exporter` property to enable it.

- Method Detail
  - createMetricReader
```
MetricReader createMetricReader(ConfigProperties config)
```
    Returns a MetricReader that can be registered to OpenTelemetry by providing the property value specified by getName().
  - getName
```
java.lang.String getName()
```
    Returns the name of this reader, which can be specified with the otel.metrics.exporter property to enable it. The name returned should NOT be the same as any other reader / exporter name, either from other implementations of this SPI or ConfigurableMetricExporterProvider. If the name does conflict with another reader / exporter name, the resulting behavior is undefined and it is explicitly unspecified which reader / exporter will actually be used.
