API to emit metering records. For identical requests, the API is idempotent. It simply returns the metering record ID.
/// A metering record has already been emitted by the same EC2 instance for the given
/// {usageDimension, timestamp} with a different usageQuantity.
///
/// An internal error has occurred. Retry your request. If the problem persists, post
/// a message with details on the AWS forums.
///
/// The endpoint being called is in a region different from your EC2 instance. The region
/// of the Metering service endpoint and the region of the EC2 instance must match.
///
/// The product code passed does not match the product code used for publishing the product.
///
/// The usage dimension does not match one of the UsageDimensions associated with products.
///
/// The calls to the MeterUsage API are throttled.
///
/// The timestamp value passed in the meterUsage() is out of allowed range.
