SWATCH-2302: Capture AWS message transmission statuses in micrometer

[awood]

Jira issue: SWATCH-2302

Description

When usage is processed by swatch-producer-aws, it increments a counter named
"swatch_producer_metered_total" with the amount in metric units, labeled with

• product (swatch product tag)
• metric_id (metric ID)
• billing_provider
• status (failed/succeeded/duplicate)

Testing

Unit tests are in the PR.

Setup

1. SERVER_PORT=8001 QUARKUS_MANAGEMENT_PORT=9001 ./gradlew :swatch-producer-aws:quarkusDev
   

Steps

1. Verify the counters are zero

   http localhost:9001/metrics | grep swatch_producer_metered_total
   

2. Produce a message for platform.rhsm-subscriptions.billable-usage-hourly-aggregate. I do it with IntelliJ, but use whatever tool you like.

   {"windowTimestamp":"2023-12-21T01:10:28Z","aggregateId": "e81bc918-6434-4a58-9192-8a8dd73ec8fb","aggregateKey": {"orgId": "org123","billingProvider": "aws","metricId": "Cores","productId": "rosa"}}

   This will produce an error since there's no AWS to communicate with

Verification

1. Repeat

   http localhost:9001/metrics | grep swatch_producer_metered_total
   

2. You'll see

   swatch_producer_metered_total{billing_provider="aws",error_code="usage_context_lookup",metric_id="Cores",product_tag="rosa",status="failed"} 0.0
   

   with the billing_provider, error_code, metric_id, product_id, and status.

Probably this was automatically done by intellij, please, avoid diamond imports.

Fixed. But I think we do use wildcards a lot in tests for static imports for JUnit, Mockito, and Hamcrest. I don't think there's an official policy on this enforced by any tooling so it would be good to reach a team consensus on this.

% rg 'import static.*\*' -l | wc -l
83

So 83 classes with wildcards and nearly all of them are in test it looks like. There are a handful in swatch-core and the main package. We should probably either fix these or at least set the style linter to catch them.

[awood]

The style guide is unambiguous about forbidding wildcard imports. So, now we just need to figure out why it's not enforcing that or if we want to as a team make an exception for org.junit, org.mockito stuff
