## background Currently, as my business is an IoT platform which serves many companies. We are trying to use pulsar functions to push messages to our customers' kafka server. Here I face the problem, the KafkaSinkConfig can only receive the `sslTruststoreLocation`. And the Kafka Client now only support `sslTruststoreLocation`.
## solution I want to add a config `sslTruststoreContent` in `KafkaIoConfig` which is a base64 decoded string. When the function starts, write the content to disk.(like conf/$tenant/$namespace/$name/sslTruststore.jks) When the function stops, delete the disk file. Thanks ZhangJian He
