What does this PR do?

Refactors logic that is used for submitting logs to Datadog.
The following improvements are done:

• Logs are submitted asynchronously now to avoid blocking execution of the core Jenkins logic
• Circuit breakers are used to avoid spamming Jenkins log with errors if log submission is configured incorrectly
• When submitting directly to Datadog intake logs are batched and compressed
• When submitting to Datadog agent, incorrect "retry" logic is no longer used
