Introduce a performance test scenario with combined datasources

Is your feature request related to a problem? Please describe.

Currently, collector does not have a performance test combining multiple datasources (traces+metrics+logs) in order to monitor the CPU and memory requirements of such scenario. In the current state of the testbed, there is no load generator providing the possibility to execute such scenario.

Since the collector is mostly used not only for isolated data types (logs/metrics/traces), but for combining all of the data types, it would be based much more on real-world usages to have a combined scenario for all data types

Describe the solution you'd like

Implement a load generator that is able to send metrics+traces+logs to be able to create a performance test combining ll 3 data sources.

Describe alternatives you've considered

No response

Additional context

Implementation of the additional combined scenario can help the community to determine the minimal requirements for running the collector in a non-isolated real-world environment as well to track the resource consumption of the collector

Could you run 3 different telemetrygen instances all pointed at the collector to perform the load with different signals? That ought to do the job, right?
