KAFKA-3417: Quote client-id and wrap reporter calls in try/catch blocks
----
> Invalid characters in config properties not being validated?
> ------------------------------------------------------------
>
> Key: KAFKA-3417
> URL: https://issues.apache.org/jira/browse/KAFKA-3417
> Project: Kafka
> Issue Type: Bug
> Components: config
> Affects Versions: 0.9.0.1
> Reporter: Byron Ruth
> Assignee: Grant Henke
> Priority: Minor
>
> I ran into an error using a {{client.id}} with invalid characters (per the
> [config
> validator|https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/common/Config.scala#L25-L35]).
> I was able to get that exact error using the {{kafka-console-consumer}}
> script, presumably because I supplied a consumer properties file and it
> validated prior to hitting the server. However, when I use a client library
> (sarama for Go in this case), an error in the metrics subsystem is thrown
> [here|https://github.com/apache/kafka/blob/977ebbe9bafb6c1a6e1be69620f745712118fe80/clients/src/main/java/org/apache/kafka/common/metrics/Metrics.java#L380].
> The stacktrace is:
> {code:title=stack.java}
