zktop default to using the ZK server’s cfg

If a ZooKeeper server is installed on the system, zktop is likely expected to connected to the ZK enseble of that and not only to the local ZK server.

• Set a default path for a ZooKeeper server configuration file to "/etc/zookeeper/conf/zoo.cfg". This value should be adapted by distributions to their respective ZooKeeper server package’s default path. • Unless “--server” is explicitly given and if the ZooKeeper server configuration file exists (is a regular file or a symlink to it) at the default path, use the later for determining to which ZooKeeper servers to connect. • Updated the documentation for these changes. • Added a note that with Python2, zktop now requires pathlib to be installed.

@phunt Hey... anything new on this?

Thanks @calestyo - tbh though I think when I looked at it originally (granted it's been a while...) I thought that I wanted to optimize for local usage as the default. I also didn't think that /etc/... was universal. Python2 should be removed entirely at this point given it's EOL for a while now.

Not sure what you mean... doesn't it make just sense to use the config if it's there and if not fall back to the current localhost usage?
