Setting up IRC channel to promote discussions and getting help

[Henry Saputra]

HI All,

Sorry for cross posting.

I thinking about setting up ASF official IRC channel for Apache Flink.

Some of us could just hang out and provide answer or just ask for
question about Flink casually.

The channel could also be used for some "official" discussions which
can be recorded and shared in the dev@ list.

If there are some interests about it I could start working on it.

I found this is useful in other projects such as Bigtop , Aurora, and Tachyon
