+/*
+Package otlpmetricgrpc provides an OTLP metrics exporter using gRPC.
+By default the telemetry is sent to https://localhost:4317.
+
+Exporter should be created using [New] and used with a [metric.PeriodicReader].
+
+The environment variables described below can be used for configuration.
+
+OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_EXPORTER_OTLP_METRICS_ENDPOINT (default: "https://localhost:4317") -
+target to which the exporter sends telemetry.
+The target syntax is defined in https://github.com/grpc/grpc/blob/master/doc/naming.md.
+The value must contain a host.
+The value may additionally a port, a scheme, and a path.
+The value accepts "http" and "https" scheme.
+The value should not contain a query string or fragment.
+OTEL_EXPORTER_OTLP_METRICS_ENDPOINT takes precedence over OTEL_EXPORTER_OTLP_ENDPOINT.
+The configuration can be overridden by [WithEndpoint], [WithInsecure], [WithGRPCConn] options.
+
+OTEL_EXPORTER_OTLP_INSECURE, OTEL_EXPORTER_OTLP_METRICS_INSECURE (default: "false") -
+setting "true" disables client transport security for the exporter's gRPC connection.
+You can use this only when an endpoint is provided without the http or https scheme.
+OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_EXPORTER_OTLP_METRICS_ENDPOINT setting overrides
+the scheme defined via OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_EXPORTER_OTLP_METRICS_ENDPOINT.
+OTEL_EXPORTER_OTLP_METRICS_INSECURE takes precedence over OTEL_EXPORTER_OTLP_INSECURE.
+The configuration can be overridden by [WithInsecure], [WithGRPCConn] options.
+
+OTEL_EXPORTER_OTLP_HEADERS, OTEL_EXPORTER_OTLP_METRICS_HEADERS (default: none) -
+key-value pairs used as gRPC metadata associated with gRPC requests.
+The value is expected to be represented in a format matching to the [W3C Baggage HTTP Header Content Format],
+except that additional semi-colon delimited metadata is not supported.
+Example value: "key1=value1,key2=value2".
+OTEL_EXPORTER_OTLP_METRICS_HEADERS takes precedence over OTEL_EXPORTER_OTLP_HEADERS.
+The configuration can be overridden by [WithHeaders] option.
+
+OTEL_EXPORTER_OTLP_TIMEOUT, OTEL_EXPORTER_OTLP_METRICS_TIMEOUT (default: "10000") -
+maximum time in milliseconds the OTLP exporter waits for each batch export.
+OTEL_EXPORTER_OTLP_METRICS_TIMEOUT takes precedence over OTEL_EXPORTER_OTLP_TIMEOUT.
+The configuration can be overridden by [WithTimeout] option.
+
+OTEL_EXPORTER_OTLP_COMPRESSION, OTEL_EXPORTER_OTLP_METRICS_COMPRESSION (default: none) -
+the gRPC compressor the exporter uses.
+Supported value: "gzip".
+OTEL_EXPORTER_OTLP_METRICS_COMPRESSION takes precedence over OTEL_EXPORTER_OTLP_COMPRESSION.
+The configuration can be overridden by [WithCompressor], [WithGRPCConn] options.
+
+OTEL_EXPORTER_OTLP_CERTIFICATE, OTEL_EXPORTER_OTLP_METRICS_CERTIFICATE (default: none) -
+the filepath to the trusted certificate to use when verifying a server's TLS credentials.
+OTEL_EXPORTER_OTLP_METRICS_CERTIFICATE takes precedence over OTEL_EXPORTER_OTLP_CERTIFICATE.
+The configuration can be overridden by [WithTLSCredentials], [WithGRPCConn] options.
+
+OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE, OTEL_EXPORTER_OTLP_METRICS_CLIENT_CERTIFICATE (default: none) -
+the filepath to the client certificate/chain trust for clients private key to use in mTLS communication in PEM format.
+OTEL_EXPORTER_OTLP_METRICS_CLIENT_CERTIFICATE takes precedence over OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE.
+The configuration can be overridden by [WithTLSCredentials], [WithGRPCConn] options.
+
+OTEL_EXPORTER_OTLP_CLIENT_KEY, OTEL_EXPORTER_OTLP_METRICS_CLIENT_KEY (default: none) -
+the filepath  to the clients private key to use in mTLS communication in PEM format.
+OTEL_EXPORTER_OTLP_METRICS_CLIENT_KEY takes precedence over OTEL_EXPORTER_OTLP_CLIENT_KEY.
+The configuration can be overridden by [WithTLSCredentials], [WithGRPCConn] option.
+
+OTEL_EXPORTER_OTLP_METRICS_TEMPORALITY_PREFERENCE (default: "cumulative") -
+aggregation temporality to use on the basis of instrument kind. Supported values:
+  - "cumulative" - Cumulative aggregation temporality for all instrument kinds,
+  - "delta" - Delta aggregation temporality for Counter, Asynchronous Counter and Histogram instrument kinds;
+    Cumulative aggregation for UpDownCounter and Asynchronous UpDownCounter instrument kinds,
+  - "lowmemory" - Delta aggregation temporality for Synchronous Counter and Histogram instrument kinds;
+    Cumulative aggregation temporality for Synchronous UpDownCounter, Asynchronous Counter, and Asynchronous UpDownCounter instrument kinds.
+
+The configuration can be overridden by [WithTemporalitySelector] option.
+
+OTEL_EXPORTER_OTLP_METRICS_DEFAULT_HISTOGRAM_AGGREGATION (default: "explicit_bucket_histogram") -
+default aggregation to use for histogram instruments. Supported values:
+  - "explicit_bucket_histogram" - [Explicit Bucket Histogram Aggregation],
+  - "base2_exponential_bucket_histogram" - [Base2 Exponential Bucket Histogram Aggregation].
+
+The configuration can be overridden by [WithAggregationSelector] option.
