Simplify output

[zaibon]

I've seen the output of the zos command are most of the time the full dump of what 0-OS returns. In most cases that's too much information for the user. We should only print the minimal information to keep a clean and clear screen. If the user wants full detail we could had an inspect command or something like docker does.

Docker is a good example of the right balance, when you list your containers, it only print the minimal useful information about them : ID, Image, created data, status, ports forwards, name. In our case not everything is the same as docker but we can pick the useful information too and print it in a nice way.

and --json parameter will show output as json
