related: #25324 Search GroupBy function, used to aggregate result entities based on a specific scalar column. several points to mention: 1. Temporarliy, the whole groupby is implemented separated from iterative expr framework **for the first period** 2. In the long term, the groupBy operation will be incorporated into the iterative expr framework:https://github.com/milvus-io/milvus/pull/28166 3. This pr includes some unrelated mocked interface regarding alterIndex due to some unworth-to-mention reasons. All these un-associated content will be removed before the final pr is merged. This version of pr is only for review 4. All other related details were commented in the files comparison Signed-off-by: MrPresent-Han <chun.han@zilliz.com>
