Datadog Connector Component (#25065)

This pull request is for a newly created Datadog connector that replaces
the need for the Datadog processor. This replacement is needed because
the processor made use of a work-around that directly allowed the
processor to export data. This is not something that adheres to the
OpenTelemetry standard and thus the previous system should be deprecated
and replaced by this new connector.
