// Get gets metric values for a single metric
// Parameters:
// appID - ID of the application. This is Application ID from the API Access settings blade in the Azure
// portal.
// metricID - ID of the metric. This is either a standard AI metric, or an application-specific custom metric.
// timespan - the timespan over which to retrieve metric values. This is an ISO8601 time period value. If
// timespan is omitted, a default time range of `PT12H` ("last 12 hours") is used. The actual timespan that is
// queried may be adjusted by the server based. In all cases, the actual time span used for the query is
// included in the response.
// interval - the time interval to use when retrieving metric values. This is an ISO8601 duration. If interval
// is omitted, the metric value is aggregated across the entire timespan. If interval is supplied, the server
// may adjust the interval to a more appropriate size based on the timespan used for the query. In all cases,
// the actual interval used for the query is included in the response.
// aggregation - the aggregation to use when computing the metric values. To retrieve more than one aggregation
// at a time, separate them with a comma. If no aggregation is specified, then the default aggregation for the
// metric is used.
// segment - the name of the dimension to segment the metric values by. This dimension must be applicable to
// the metric you are retrieving. To segment by more than one dimension at a time, separate them with a comma
// (,). In this case, the metric data will be segmented in the order the dimensions are listed in the
// parameter.
// top - the number of segments to return.  This value is only valid when segment is specified.
// orderby - the aggregation function and direction to sort the segments by.  This value is only valid when
// segment is specified.
// filter - an expression used to filter the results.  This value should be a valid OData filter expression
// where the keys of each clause should be applicable dimensions for the metric you are retrieving.
