Fix docker compose & quick start

[konradmalik]

Quick start for docker does not currently work.

1. default network created by compose starts with the name of the parent dir. So it is "pinot_default", not "docker_default". Scripts in README were fixed according to that.
2. docker-compose -f docker-compose up does not start the stack properly. Services complain about connectivity issues, which trace back to zookeeper. Turns out (probably a change in the newer version, as docker-compose users "latest" tag) ZOO_SERVERS need a listening port at the end. This is also now fixed.

Now users can simply follow Quick Start instructions and all will work "out of the box".
