Reduce log level for optimistic lease update fallback

Browse Source 
The "Failed to update lease optimistically, falling back to slow path"
message was logged at Error level, but this is expected behavior during
normal leader election when the optimistic update encounters a conflict.
The system gracefully falls back to the slow path (Get + Update), so
this is not a real error. Downgrade to V(2) Info to reduce log noise.
