Move the exclude nodes clearing logic from ExecuteWithRetry to
selectNode after shard leader cache refresh to ensure proper retry
behavior:
- Remove premature exclude clearing in ExecuteWithRetry that happened
before shard leader cache update
- Add exclude clearing logic in selectNode after refreshing shard leader
cache when all replicas are excluded
- Ensure multiple retries can properly update shard leader cache and
clear exclude list when needed
- Add comprehensive tests for edge cases including empty shard leaders
and mixed serviceable node scenarios

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.

The absent nullable field shall be filled at server-side in nullable
design. While the implementation here was buggy causing the feature was
not able to serve.
This PR make proxy fill the field data in correct format so that field
data with absent column(s) will be accepted.

1. Optimizing decay function
2. Since the decay function is larger, the more similar it is， the
smaller the L2/JACCARD/HAMMING metrics scores the more similar they are.
For these metrics, the decay function regenerates new scores.
