TANU-000004 Introduce cache for BIN result

[neko32]

Overview

Currently Bin service doesn't have cache for the result. Bin service should use cache to reduce IO with external BIN info service. However, service should NOT disrupt its operation if data fetch from cache fails

TODO

• choose a way to support cache (local mem, Redis etc,.)
• implement the cache feature for BIN service
• add unit test
• no fallback for failure case - mishit or failure will lead to a http call to external Bin service

Success Criteria

• same BIN data queries' results are retuned from cache
• add unit tests and proper test coverage
• make sure fallback situation won't disrupt bin retrieval operation
