STORM-3123: Storm Kafka Monitor cannot connect to Kafka over two-way SSL
### What is this PR for?
This PR introduces a new configuration option "--consumer-config" (or "-c")
in KafkaOffsetLagUtil to connect to Kafka Broker over two-way SSL. New option
expects a configuration file containing security properties for Kafka.
Behavior without this PR:
When Kafka broker is running with two-way SSL (i.e.
ssl.client.auth=required), Storm Kafka monitor would fail to connect to Kafka
with this error:
`Warning: no suitable certificate found - continuing without client
authentication
*** Certificate chain
<Empty>
***`
Behavior with this PR:
KafkaOffsetLagUtil can now query offset lag for Kafka spout with 2-way SSL
authentication
### What type of PR is it?
[Bug Fix]
### What is the Jira issue?
* https://issues.apache.org/jira/browse/STORM-3123
### How should this be tested?
1. Configure Kafka Broker with 2-way SSL authentication (make sure that
ssl.client.auth=required is set in the broker configuration)
2. Create a topic 'testoffset' and produce some messages to it.
3. Run KafkaOffsetLagUtil from command line:
`/usr/jdk64/jdk1.8.0_77/bin/java -cp
/root/storm-kafka-monitor-1.1.0.2.6.3.0-SNAPSHOT.jar
org.apache.storm.kafka.monitor.KafkaOffsetLagUtil -t testoffset -g testgroup -b
node2.openstacklocal:6669 --security-protocol SSL --consumer-config
./consumer.properties`
where the file consumer.properties contains:
ssl.truststore.location=/tmp/kafkaCert/client.truststore.jks
ssl.truststore.password=password
ssl.keystore.location=/tmp/kafkaCert/client.keystore.jks
ssl.keystore.password=password
security.protocol=SSL
4. KafkaOffsetLagUtil would show correct offset log from Kafka topic
'testoffset'.
