Execute

Session::execute is almost the same as Session::query, the difference is execute won't return ResultSet.
The signature of Session::execute is:

seastar::future<> execute(Command&& command);

For example:

auto command = cql::Command("insert into exmple_ks.my_table (id, name) values (?,?)")
	.addParameters(cql::Int(1), cql::Text("a"));
session.execute(std::move(command)).then([] {
	std::cout << "insert was successful" << std::endl;
});

Session::execute can take select statement even it's meanless, and Session::query can take insert or update statements. In other words, if you don't care a slight difference in performance, you can always use Session::query to perform database operations.
