Add --context flag

[cykl]

Kafkactl currently supports multiple contexts. To use a context, one must use kubectl config use-context aws-dev.

This is often fine, but it also has following drawbacks:

• Active context is not explicit in a command line. You must know the active context to asset what a command will do.
• It's often annoying having to type two commands when one could suffice.

Have you ever thought about introducing a --context flag (similar to kubectl). An explicit --context would take precedence over anything else. People enjoying how it works today can continue to do so, and people who prefer to set the context with every command will be happy to.

hey @cykl

I think its a good idea. Its not already there because I personally did not have such a use case, yet.
It should be fairly easy to implement. Starting point would be to add it to the global configs here:

Thanks for the feedback.

That's a good excuse to learn some go. I'll submit a PR.

Yes really useful for us also. use-context requires having write permissions on the config file which we don't want to give.
