* Introduce api/send Added events and requests for support. Reworked delivery_monitor into a featured devlivery_service, that - supports relay publish and lightpush depending on configuration but with fallback options - if available and configured it utilizes store api to confirm message delivery - emits message delivery events accordingly prepare for use in api_example * Fix edge mode config and test added * Fix some import issues, start and stop waku shall not throw exception but return with result properly * Utlize sync RequestBroker, adapt to non-async broker usage and gcsafe where appropriate, removed leftover * add api_example app to examples2 * Adapt after merge from master * Adapt code for using broker context * Fix brokerCtx settings for all usedbrokers, cover locked node init * Various fixes upon test failures. Added initial of subscribe API and auto-subscribe for send api * More test added * Fix multi propagate event emit, fix fail send test case * Fix rebase * Fix PushMessageHandlers in tests * adapt libwaku to api changes * Fix relay test by adapting publish return error in case NoPeersToPublish * Addressing all remaining review findings. Removed leftovers. Fixed loggings and typos * Fix rln relay broker, missed brokerCtx * Fix rest relay test failed, due to publish will fail if no peer avail * ignore anvil test state file * Make terst_wakunode_rln_relay broker context aware to fix * Fix waku rln tests by having them broker context aware * fix typo in test_app.nim
