Does this support SASL_SSL.

Discussed in #9.

TL;DR: Possibly, but not tested.

@ekoutanov
after i added some code on KafkaHighLevelAdminClient.java, it works well for me.
add the following after line28
if (kafkaConfiguration.getIsSecured()) {
props.put(CommonClientConfigs.SECURITY_PROTOCOL_CONFIG, kafkaConfiguration.getSecurityProtocol());
props.put(SaslConfigs.SASL_MECHANISM, kafkaConfiguration.getSaslMechanism());
}

another issue is exception occurred when show cluster-overview and broker detail page since host in BrokerVO which was got from kafkaMonitor.getBrokers() is null.
also i found a similar case as below.
Yelp/kafka-utils#157

revise the following parts, it works well.
cluster-overview.ftl
line92
${b.host?if_exists}
broker-detail.ftl
line42
${broker.host?if_exists}:${broker.port}

i tried to create a branch and then create pullrequest, it seems no auth for me to do that.

Hi @shaaimin. To a PR, it's best to fork the repo, make your change into your master, then raise the PR.
