Description:
Make Datadog exporter source providers run in parallel to reduce start times. With the new
Chain
implementation, we start checking all sources in parallel instead of waiting for the previous one to fail. This makes the Datadog exporter call all cloud provider endpoints in all cloud providers, so it may increase spurious logs such as those reported in #24072.Link to tracking Issue: Updates #16442 (at least it should substantially improve start time in some environments)
Testing: Added unit test
Documentation: Performance improvement, no new docs needed
