change message envelopes and encoding, unify message delivery (#252)
* types and encodings for double ratchet integration

* upgrade stack resolver

* type classes for version agreement, encode/decode connection request links and E2E params with versioning

* encode/decode client parameters (version and DH key) in SMP queue URI using query string parameters

* restore support of the current SMP queue URI format

* update AMessage to only send queues in REPLY message (not the full connection request)

* new agent message evnvelopes (tests fail)

* new message envelopes - tests pass

* store fully encrypted messages before sending

* unify message delivery via DB queue (excluding confirmation and invitation)

* remove activateSecuredQueue

* linter hints

* remove comment

* export order

* save rachet-encrypted message, not per-queue encrypted

* delete message after it is accepted by the server, reduce message delivery interval for the tests
