Description

Add StatusDataset client functionality into ndn::nfd::Controller.

Currently, ndn::nfd::Controller contains a client for NFD ControlCommand.
An application can easily execute a command on the local NFD with controller.start<FaceCreateCommand>, and need not know the details such as the exact name for this command.

However, there's a disparity for NFD StatusDataset, which is another major part of NFD Management protocol.
An application must manually construct the name of a dataset, use SegmentFetcher to obtain the contents, and then manually parse the dataset.

To simplify applications, StatusDataset client shall be integrated into ndn::nfd::Controller.

An application can request a dataset using a syntax like:

controller.fetch<FaceDataset>(onSuccess, onFailure, options);
controller.fetch<FaceQueryDataset>(faceQueryFilter, onSuccess, onFailure, options);

The API I have in mind is:

// for datasets without parameter, such as FIB
template<typename Dataset>
fetch(std::function<void(Dataset::ResultType)>, CommandFailCallback, CommandOptions);

// for datasets with parameter, such as face query
template<typename Dataset>
fetch(Dataset::ParameterType, std::function<void(Dataset::ResultType)>, CommandFailCallback, CommandOptions);

// ResultType is the full dataset (usually a vector), not a single element
// CommandFailCallback and CommandOptions can be renamed as necessary
