/**
 * Execute the given command for each key in {@code keys} provided appending all {@code args} on each invocation.

 * This method, other than {@link #execute(String, byte[]...)}, dispatches the command to the {@code key} serving
 * master node and appends the {@code key} as first command argument to the {@code command}. {@code keys} are not
 * required to share the same slot for single-key commands. Multi-key commands carrying their keys in {@code args}
 * still require to share the same slot as the {@code key}.
 *
 * <pre>
 * <code>
 * // SET foo bar EX 10 NX
 * execute("SET", "foo".getBytes(), asBinaryList("bar", "EX", 10, "NX"))
 * </code>
 * </pre>
 *
 * @param command must not be {@literal null}.
 * @param keys must not be {@literal null}.
 * @param args must not be {@literal null}.
 * @return command result as delivered by the underlying Redis driver. Can be {@literal null}.
