[services] Tunnelbroker - Fix IDs in Terraform dynamodb table attributes

Summary:
This diff is a fix.
After updating the field names to use ID instead of Id some of the fields used the old names which caused errors while running in the cloud. The codebase is already
using the ID pattern. The changes need to be made in the Terraform script.

Linear task: ENG-1492

Test Plan: Run yarn init-local-cloud and run database related unit tests in test/DatabaseManagerTest.cpp.
