KafkaClient should not refresh metadata when broker socket is closed …

[hyperlink]

…due to being idle

It appears this test fails on all builds in Travis 🔨
#removeTopics
1) "after all" hook: close consumer group

This will cause:

kafka-node:KafkaClient kafka-node-client to 192.168.0.151:9092 is idle not reconnecting +10m

What do you think about adding a param to force reconnecting when idle in this scenario?

Something like new KafkaClient({ reconnectOnIdle: true })

Yup that is one of the flaky tests. 😒

Something like new KafkaClient({ reconnectOnIdle: true })

Not against adding this. PR?
