Add connector usage to the testbed (open-telemetry#32881)
**Description:** Added a new component to the testbed called DataConnectors which allows connectors to be added to the testbed config. Also, added a sample connector correctness test using the routingconnector as an example of the usage. **Link to tracking Issue:** open-telemetry#30165 **Testing:** Sample correctness test using routingconnector. **Documentation:** Will update the testbed README with new addition. --------- Co-authored-by: Bryan Aguilar <bryaag@amazon.com>
