Please resolve the conflict with the latest master branch.

Is 9080 port just for liveness check?

[RoySRose]

1. Is port 9080 only for checking liveness?
2. There was a cleanup on environment variables in the docker image of v2.1.0 Pinpoint. You can see the list under pinpoint-collector in the docker-compose file (https://github.com/naver/pinpoint-docker/blob/master/docker-compose.yml). The differences I found so far are below

• externalZookeeperAddress can be renamed to something like pinpoint zookeeper address
• externalHbaseAddress is not necessary
• I can see Values.externalZookeeperAddress in the values.yaml but where is Values.flink.zookeeperAddress? flink zookeeper address is necessary
• I don't think Hbase_port is also necessary.

(I think there were a few more things. But can't remember after my former reply was mistakenly deleted. I'll update as soon as I remember)
