1. Optimize the import process: skip subsequent steps and mark the task
as complete if the number of imported rows is 0.
2. Improve import integration tests:
a. Add a test to verify that autoIDs are not duplicated
b. Add a test for the corner case where all data is deleted
c. Shorten test execution time
3. Enhance import logging:
a. Print imported segment information upon completion
b. Include file name in failure logs

Implement dynamic task execution capacity calculation based on QueryNode
CPU core count instead of static configuration for better resource
utilization.
Changes include:
- Add CpuCoreNum() method and WithCpuCoreNum() option to NodeInfo
- Implement GetTaskExecutionCap() for dynamic capacity calculation
- Add QueryNodeTaskParallelismFactor parameter for tuning
- Update proto definition to include cpu_core_num field
- Add unit tests for new functionality
This allows QueryCoord to automatically adjust task parallelism based on
actual hardware resources.

This commit implements partial search result functionality when query
nodes go down, improving system availability during node failures. The
changes include:
- Enhanced load balancing in proxy (lb_policy.go) to handle node
failures with retry support
- Added partial search result capability in querynode delegator and
distribution logic
- Implemented tests for various partial result scenarios when nodes go
down
- Added metrics to track partial search results in querynode_metrics.go
- Updated parameter configuration to support partial result required
data ratio
- Replaced old partial_search_test.go with more comprehensive
partial_result_on_node_down_test.go
- Updated proto definitions and improved retry logic
These changes improve query resilience by returning partial results to
users when some query nodes are unavailable, ensuring that queries don't
completely fail when a portion of data remains accessible.

Large nq will naturally increase query time, which causing lots of slow
log when user NQ numbers are very large.
This PR make slow search counts span per nq (using avg val) to decide
whether one request is slow or not.

Optimize session management by reducing the TTL (Time To Live) value for
service registration from 30 seconds to 10 seconds. This change improves
the system's ability to detect service failures more quickly and
enhances overall cluster responsiveness.
Changes include:
- Update default session TTL from 30s to 10s in milvus.yaml
- Adjust DefaultSessionTTL constant from 30 to 10 seconds
- Update SessionTTL default value from 60 to 10 seconds
- Maintain consistent TTL values across configuration files
This optimization reduces the time required for the system to detect
when services become unavailable, leading to faster failover and
improved cluster stability during node failures or network issues.
