Add impressions dependency to client/pom.xml. Add adapter classes TelemetryRuntimeImpressionsRecorder and TelemetryUniqueKeysSender to bridge the old telemetry interfaces to the new impressions module boundaries. Update SplitFactoryImpl to build ImpressionsManagerConfig and use the adapters when constructing ImpressionsManagerImpl and UniqueKeysTrackerImp. Move strategy tests and UniqueKeysTrackerImpTest to the impressions module where their dependencies now live.

Extracted impressions module. Murmur3 implementation was copied to prevent coupling to targeting-engine module (one class only).
