Describe the bug

Currently, vmagent data ingestion into kafka is limited by network latency. And if brokers respond with delay, overall throughput is limited by a slowest broker.

I propose to introduce a concurrency setting, as we already have for kafka consumer. It should have default value of 1 and could be increased if needed.

vmagent must start worker per concurrency setting and perform client side round-robin balancing.

To Reproduce

start kafka cluster with brokers at high latency network.

Version

any version of vmagent with kafka
