FLUME-2857. Make Kafka Source/Channel/Sink restore default values when live
updating config
This commit changes Kafka Channel, Sink and Source to fix an error where
sub-configurations aren't tolerant of the configure() method being called more
than once (as happens when a Live Config Update happens).

> Been using the following config:
> {noformat}
> tier1.channels.channel1.type = org.apache.flume.channel.kafka.KafkaChannel
> tier1.channels.channel1.capacity = 10000
> tier1.channels.channel1.transactionCapacity = 10000
> tier1.channels.channel1.brokerList =
> 10.0.0.64:9092,10.0.0.65:9092,10.0.0.66:9092
> tier1.channels.channel1.topic = flume.aggregator.channel
> tier1.channels.channel1.zookeeperConnect = 10.0.0.64:2181
> tier1.channels.channel1.kafka.producer.type=async
> tier1.channels.channel1.kafka.batch.num.messages=200
> {noformat}
> If I remove the producer.type and batch.num.messages (i.e. restore them to
> default values) when doing a live update config the new values do not take
> effect.
