[Task] simplify the use of client annotations with @AliasFor

[loongs-zhang]

Description

For example, below is how we use @ShenyuXXXXClient now:

@RestController
@RequestMapping("/order")
@ShenyuSpringCloudClient(path = "/order")
public class OrderController {

    /**
     * Save order dto.
     *
     * @param orderDTO the order dto
     * @return the order dto
     */
    @PostMapping("/save")
    @ShenyuSpringCloudClient(path = "/save")
    public OrderDTO save(@RequestBody final OrderDTO orderDTO) {
        orderDTO.setName("hello world spring cloud save order");
        return orderDTO;
    }

}

After use @AliasFor with @ShenyuSpringCloudClient like below:

@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.TYPE, ElementType.METHOD})
public @interface ShenyuSpringCloudClient {

    /**
     * Path string.
     *
     * @return the string
     */
    @AliasFor(attribute = "path")
    String value() default "";

    /**
     * Path string.
     *
     * @return the string
     */
    @AliasFor(attribute = "value")
    String path() default "";

    /**
     * Rule name string.
     *
     * @return the string
     */
    String ruleName() default "";

    /**
     * Desc string.
     *
     * @return String string
     */
    String desc() default "";

    /**
     * Enabled boolean.
     *
     * @return the boolean
     */
    boolean enabled() default true;
}

We can simplify client annotation usage to:

@RestController
@RequestMapping("/order")
@ShenyuSpringCloudClient("/order")
public class OrderController {

    /**
     * Save order dto.
     *
     * @param orderDTO the order dto
     * @return the order dto
     */
    @PostMapping("/save")
    @ShenyuSpringCloudClient("/save")
    public OrderDTO save(@RequestBody final OrderDTO orderDTO) {
        orderDTO.setName("hello world spring cloud save order");
        return orderDTO;
    }

}

You can refer to the implementation scheme of shenyu-client-springcloud, don't forget to use org.springframework.core.annotation.AnnotatedElementUtils#findMergedAnnotation.
