fix(accountingservice): fix graceful shutdown and log issues

[tranngoclam]

Changes

• Add 2 missing signals (SIGTERM: when docker compose stop, SIGKILL: when docker compose rm) for handling graceful shutdown.
• Fix structured log in consumer

Example when app starts and stops by docker stop accounting-service

docker logs -f accounting-service

@puckpuck and @fatsheep9146, not sure if you have seen this, but after this PR and #1400 got merged, the Trace is now broken:

Checkoutservice call should be part of the Place Order trace, as it always was.

Did I miss something?

[julianocosta89]

I vote in reverting this and #1400.
