Introduce an optional Predicate<String> targetAttributeFilter to control how grpc.target is recorded in OpenTelemetry client metrics. When a filter is provided, targets rejected by the predicate are normalized to "other" to reduce grpc.target metric cardinality, while accepted targets are recorded as-is. If no filter is set, existing behavior is preserved. This change adds a new Builder API on GrpcOpenTelemetry to allow applications to configure the filter. Tests verify both the Builder wiring and the target normalization behavior. This is an optional API; annotation (e.g., experimental) can be added per maintainer guidance.
