conductor oss v3.21.19 cannot send metrics to datadog

**Describe the bug**
Conductor is deployed to k8s with below settings

```
conductor.metrics-datadog.enabled=true
management.datadog.metrics.export.enabled=true
management.datadog.metrics.export.apiKey=${DD_API_KEY}
management.datadog.metrics.export.application-key=${DD_APP_KEY}
management.datadog.metrics.export.uri=
management.datadog.metrics.export.step=10s
management.metrics.tags.env=test
```

Above works fine until I upgrade from v3.21.14 to v3.21.19 - conductor metrics cannot be sent to datadog dashboards.
Every config keep the same, I revert back to v3.21.14 - conductor metrics can be sent and shown in datadog dashboards

v3.21.19 at start up it has logs:
```
9302 [main] INFO com.netflix.conductor.contribs.metrics.MetricsCollector [] - =========
9302 [main] INFO com.netflix.conductor.contribs.metrics.MetricsCollector [] - Conductor configured with 4 metrics registries

```
but in v3.21.14 there are no such logs printed.

I also noticed that settings.gradle v3.21.19 removed below dependency. Just for your reference.
include 'client'
include 'client-spring'
