issue: #34357
Go Parquet uses dictionary encoding by default, and it will fall back to
plain encoding if the dictionary size exceeds the dictionary size page
limit. Users can specify custom fallback encoding by using
`parquet.WithEncoding(ENCODING_METHOD)` in writer properties. However,
Go Parquet [fallbacks to plain
encoding](e65c1e295d/go/parquet/file/column_writer_types.gen.go.tmpl (L238))
rather than custom encoding method users provide. Therefore, this patch
only turns off dictionary encoding for the primary key.
With a 5 million auto ID primary key benchmark, the parquet file size
improves from 13.93 MB to 8.36 MB when dictionary encoding is turned
off, reducing primary key storage space by 40%.

The parsing delete log is distributed in lots of places, which is not
recommended and hard to maintain.
This PR abstract common parsing logic into `DeleteLog.Parse` method to
unify implementation and make it easier to replace json parsing lib.

Feature Introduced:
1. Ensure ImportV2 waits for the index to be built
Enhancements Introduced:
1. Utilization of local time for timeout ts instead of allocating ts
from rootcoord.
3. Enhanced input file length check for binlog import.
4. Removal of duplicated manager in datanode.
5. Renaming of executor to scheduler in datanode.
6. Utilization of a thread pool in the scheduler in datanode.

This PR introduces novel importv2 roles for datanode:
1. Executor: To execute tasks, a import task will be divided into the
following steps: read data -> hash data -> sync data;
2. Manager: To manage all the tasks;
