apache#25500) Support aggregate functions in select without from clause, here are some examples as following: SELECT 1, 'a', COUNT(), SUM(1) + 1, AVG(2) / COUNT(), MAX(3), MIN(4), RANK() OVER() AS w_rank, DENSE_RANK() OVER() AS w_dense_rank, ROW_NUMBER() OVER() AS w_row_number, SUM(5) OVER() AS w_sum, AVG(6) OVER() AS w_avg, COUNT() OVER() AS w_count, MAX(7) OVER() AS w_max, MIN(8) OVER() AS w_min;

could not run multi group_concat distinct with more than one parameters. This bug is not just for group_concat, but we usually use literal as parameters in group_concat. So group_concat brought the problem to light. In the original logic, we think only distinct aggregate function with zero or one parameter could run in multi distinct mode. But it is wrong. We could process all distinct aggregate function with not more than one input slots. Think about sql: ```sql SELECT group_concat(distinct c1, ','), group_concat(distinct c2, ',') FROM t GROUP BY c3 ```
…#26003) The image file of our cluster reaches 2.3G. After the checkpoint, Followers synchronize the image timeout, resulting in the continuous increase of the bdb directory. related pr: apache#25768

apache#25847) Doris is not responsible for managing snapshots, but it needs to clear all snapshots before doing backup/restore regression testing, so a property is added to indicate that existing snapshots need to be cleared when creating a repo.

… type (apache#25470) Previously,doris's `DateTimev2` was exported to orc as a `String` type. Now, export doris's `DateTimev2` to orc timestamp type.
…e#25727) In previous, when using file scan node(eq, querying hive table), the max number of scanner for each scan node will be the `doris_scanner_thread_pool_thread_num`(default is 48). And if the query parallelism is N, the total number of scanner would be 48 * N, which is too many. In this PR, I change the logic, the max number of scanner for each scan node will be the `doris_scanner_thread_pool_thread_num / query parallelism`. So that the total number of scanners will be up to `doris_scanner_thread_pool_thread_num`. Reduce the number of scanner can significantly reduce the memory usage of query.
example: set ignore_runtime_filter_ids="3, 1"; after this setting, RF003 and RF001 will be ignored
