Create a metric sample containing the same value as the specified `original` sample. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. Note that copying the contained `MetricSampleGroup` objects copies only the pointers to their respective `MetricRecord` arrays, and does not copy the records themselves; hence, these record arrays must remain valid for the productive lifetimes of all copied objects or until the records are removed by calling `removeAllRecords`.
