// List lists the usage details for a scope by billing period. Usage details are available via this API only for May 1,
// 2014 or later.
// Parameters:
// scope - the scope of the usage details. The scope can be '/subscriptions/{subscriptionId}' for a
// subscription, or
// '/subscriptions/{subscriptionId}/providers/Microsoft.Billing/billingPeriods/{billingPeriodName}' for a
// billing period.
// expand - may be used to expand the properties/additionalProperties or properties/meterDetails within a list
// of usage details. By default, these fields are not included when listing usage details.
// filter - may be used to filter usageDetails by properties/usageEnd (Utc time), properties/usageStart (Utc
// time), properties/resourceGroup, properties/instanceName or properties/instanceId. The filter supports 'eq',
// 'lt', 'gt', 'le', 'ge', and 'and'. It does not currently support 'ne', 'or', or 'not'.
// skiptoken - skiptoken is only used if a previous operation returned a partial result. If a previous response
// contains a nextLink element, the value of the nextLink element will include a skiptoken parameter that
// specifies a starting point to use for subsequent calls.
// top - may be used to limit the number of results to the most recent N usageDetails.
