Any benchmarks around data drops

[chaudhary-harsh]

Are there any benchmarks to measure if and under what conditions this plugin might be dropping data that it reads from Kafka or writes to TSDB.

This is somehow related to #2 as well

There are a lot of stats that it will output. Everything starting with tsd.plugin.KafkaStorageExceptionHandler and by making calls to https://github.com/OpenTSDB/opentsdb-rpc-kafka/blob/master/src/main/java/net/opentsdb/tsd/KafkaHttpRpcPlugin.java#L86-L88
