Description

Please describe the feature request. Send metrics to the Datadog API with the same format the datadog agent uses. More specifically sending counts as rate metrics.

Rationale If you've created a metric/custom metric as a count using Datadog's agent/dogstatsd, it will have the type of Rate interval=10 in Datadog by default. Not only does it transmit the values this way, it actually divides the values provided by 10 in the data series -- https://docs.datadoghq.com/api/latest/metrics/#submit-metrics. So when you submit the same metric using the micrometer integration direct to the API the values are multiplied by 10.

It would be great to have a configuration to send metrics using Micrometer with the same format as the Datadog agent sends.

Additional context Very similar to this issue with Telegraph: https://github.com/influxdata/telegraf/issues/10944

We have some applications that send the metrics to the agent using micrometer-registry-statsd and would like to have the same behavior when sending with micrometer-registry-datadog

Contributor guide

Research direction
Investigate how the Datadog agent submits count metrics (rate interval) and compare with the current implementation in micrometer registry datadog. Identify the differences in metric formatting and submission, and propose changes to optionally match the agent's behavior.
