vine: rename logs

[JinZhou5042]

In TaskVine, we can assign a path as the top-level entry for all logs, like

m = Manager(run_info_path="vine-run-info")

But there is no method to rename each yyyy-mm-dd formatted entry under this directory, such as:

drwxr-xr-x 4 jzhou24 campus 4.0K Sep 26 13:22 2024-09-26T132240
drwxr-xr-x 4 jzhou24 campus 4.0K Sep 26 13:23 2024-09-26T132301
drwxr-xr-x 4 jzhou24 campus 4.0K Sep 26 13:23 2024-09-26T132315
drwxr-xr-x 5 jzhou24 campus 4.0K Sep 26 13:23 2024-09-26T132357
lrwxrwxrwx 1 jzhou24 campus   51 Sep 26 13:23 most-recent -> /scratch365/jzhou24/vine-run-info/2024-09-26T132357
drwxr-xr-x 2 jzhou24 campus 4.0K Sep 26 13:22 vine-cache

Adding a method to rename these subdirectories directly in the code would make it easier to label each entry based on specific settings, and can relieve users from distinguishing logs on checking.
