URL: https://github.com/apache/doris/pull/22130
## Proposed changes
The lazy open goal is to reduce num of open partition, but it useless,
test case:
CREATE TABLE test_partition_version (
TIME_STAMP datev2 NOT NULL COMMENT '采集日期'
) ENGINE=OLAP
DUPLICATE KEY(TIME_STAMP)
COMMENT 'OLAP'
PARTITION BY RANGE(TIME_STAMP)
(
PARTITION p20221220 VALUES [('2022-12-20'), ('2022-12-21')),
PARTITION p20221221 VALUES [('2022-12-21'), ('2022-12-22'))
)
DISTRIBUTED BY HASH(TIME_STAMP) BUCKETS 10
PROPERTIES
(
"replication_allocation" = "tag.location.default: 1"
);
insert into test_partition_version values ('2022-12-20')
when open lazy open

when close lazy open
The action is the same with config lazy open.only written partition version
is added and commit to FE.

Therefore, it unnecessary to use lazy open.
