[Adaptive Server Selector] Extend the HYBRID type to cover query failures

[MeihanLi]

Current HYBRID type takes two factors into considerations: query latency and number of inflight requests. We can also count query failures on each server when calculating server scores, the same as number of inflight requests. As it can help detect issues on certain servers such as schema mismatch, etc.

I think this was covered in https://github.com/apache/pinot/pull/14029 (but uses latency penalty instead of query failure count)
