commit 0c694cfdc9b11f915f1da86260ad3655c2e99a35
Author: Qiang Zhao <74...@users.noreply.github.com>
AuthorDate: Tue Apr 26 22:11:35 2022 +0800

    [improve][common] Use `Collection` to instead of `List` parameter type (#15329)
    
    ### Motivation
    
    We can use `Collection` instead of `List` parameter type in `FutureUtil` for better compatibility.
    For example when we need to use the values of `Map`:
    
    ```java
    FutureUtil.waitForAll(map.values());
    ```
    ### Modifications
    
    - Use `Collection` instead of `List` parameter type.
