THe querynode pipeline will make map & call ProcessInsert when there is
no write messages. So querynodes will have high CPU usage even when
there is no workload.

add scalar filtering and vector search latency metrics to distinguish
the cost of scalar filtering.
To add metrics in query chain, add a monitor module and move the metric
files from original storage module.

Seals the largest growing segment if the total size of growing segments
of each shard exceeds the size threshold(default 4GB). Introducing this
policy can help keep the size of growing segments within a suitable
level, alleviating the pressure on the delegator.

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%.

When consuming insert data on the delegator node, QueryCoord will move
out some sealed segments to manage its memory usage. After the growing
segment gets flushed, some sealed segments from other workers will be
moved back to the delegator node. To avoid the frequent movement of
segments, we estimate the maximum growing row count and preserve a
fixed-size memory in the delegator node.
