Add option to specify cert / key location for kafka

[bputt]

Description

Currently when setting up the kafka indexing service, we're only able to provide the following and would be nice if we can also specify the certificate/key

ioConfig: {
    consumerProperties: {
        "ssl.truststore.password": "",
        "ssl.keystore.password": "",
        "ssl.key.password": ""
    }
}

Motivation

The documentation ins't exactly clear how to use kafka indexing service with tls enabled kafka brokers. It would be nice if there was a way to specify the cert & key or if it's already possible, just updating documentation.

@bputt , @adilev26, is there an instruction on how to setup the key/certificate of the kafka indexing service to be able to consume from Kafka via TLS?

hi @Samlinxia , technically you can put any property of Kafka inside that block of config and it will pass on to the Kafka consumer as is.
I just put the following and it worked:
"security.protocol": "SSL",
"ssl.truststore.location": "{location of my .jks file}"
