Create a HistogramVec and registers to default registry.

§Examples

let opts = histogram_opts!("test_macro_histogram_vec_1", "help");
let histogram_vec = register_histogram_vec!(opts, &["a", "b"]);
assert!(histogram_vec.is_ok());

let histogram_vec =
    register_histogram_vec!("test_macro_histogram_vec_2", "help", &["a", "b"]);
assert!(histogram_vec.is_ok());

let histogram_vec = register_histogram_vec!("test_macro_histogram_vec_3",
                                            "help",
                                            &["test_label"],
                                            vec![0.0, 1.0, 2.0]);
assert!(histogram_vec.is_ok());
