KIP-749 — Add --files and --file-separator options to the ConsoleProducer

Discussion ProducerAdmin

Adds `--files` and `--file-separator` options to `kafka-console-producer.sh` to allow bulk-producing records from one or more files in a single invocation. Currently the console producer can only read from stdin or a single file via shell redirection, requiring complex shell scripting to ingest multiple log files.
