3. Removing directory:
If you want the delete recursively then you have to pass a second `true` parameter
to rmdir and supply a key. This key will be treated as a prefix. All keys that match the
prefix will be deleted. All deleted keys will be placed in `response.values()` and
`response.keys()`. This parameter defaults to `false`.

etcd::Client etcd("http://127.0.0.1:2379");
etcd.set("/test/key1", "foo");
etcd.set("/test/key2", "bar");
etcd.set("/test/key3", "foo_bar");
etcd::Response resp = etcd.rmdir("/test", true).get();
for (int i = 0; i < resp.keys().size(); ++i)
{
std::cout << resp.keys(i);
std::cout << " = " << resp.value(i).as_string() << std::endl;
}

However, if recursive parameter is false, functionality will be the same as just deleting a key.
The key supplied will NOT be treated as a prefix and will be treated as a normal key name.
