JSON/YAML output for CLI commands

[kosmoz]

All CLI commands should support specifying an output format if applicable. This can be done using the --output flag (short: -o). This flag is optional (default: empty) and can be set to "json" or "yaml". Output should be written to STDOUT.

If a command modifies some resources, the output should be of the resource after modification.
Those commands should also provide a --dry-run option.

Examples

# list packages as yaml
glasskube ls -o yaml
# simulate install and write json output to a file
glasskube install foo-pkg --dry-run --output=json > foo.json

All yours!

Hi @Aryakoste, we created some subtasks now, since these are a lot of separate tasks. Could you please pick one of the linked issues, then we'll re-assign you to that, thanks!

[Aryakoste]

@christophenne can I work on multiple tasks.

[christophenne]

@Aryakoste which tasks would you like to do?

[Aryakoste]

I can work on update and configure commands tasks. @christophenne

[christophenne]

I think you can start with #657 and #658 – usually we try to have contributors work at only one issue at a time, but in this case it makes a bit more sense because the tasks are similar.

Can you please shortly comment in these two? I think you need to be "active" in the issue, otherwise github does not allow me to assign you it seems.

I have commented in the above 2 issues.
