Fly: Deduplicate & use persistent queue for incoming VAAs (#28)

* Deduplication of vaas messages
Use persistent queue for vaas messages (except for pyth)
Add local flag for local execution (use a memory queue)

* Improve names for consumers
Add deduplication in memory for all vaas messages and tests
Split incoming vaas (pyth and non pyth) into different channels and tests

* Check if queue message is expired

* Code review updates
