chore: initial import from sless/shared-sqs (v0.1.14)

- Standalone SQS-service repository
- Multi-tenant message queue service, AWS SQS compatible
- Based on GoAws, with mutable tenants, auth, WebUI, Redis persistence
- Ready for independent development and deployment
- See doc/ and README.md for architecture and usage
