Unified Logging for network

[Yasumasa Suenaga]

Hi all,

We need to out UL to stdout and/or file. If we can out it to TCP socket, I think it is useful.

For example, some system gather all logs to document oriented databases (e.g. Elasticsearch) and/or cloud monitoring platform (e.g. CloudWatch). If HotSpot can out UL to TCP socket, we can send all logs to them via TCP input plugin (Fluentd, Logstash).

I think it is useful for container platform. What do you think?
If it is worth to work, I will add CSR and JBS ticket, and also will create patch.
