Thanks, Paul!

I don't feel particularly strong about this, but some nits:

• I preferred instance to context. Whats the rationale behind context?
• I don't like having the tool modify the config; this doesn't work well for kubectl as it looses all the formatting. I'd prefer the config be static, have the ability to specify a default instance in the config, and pick a config on a per command basis (doing --instance=dev etc)

WDYT?

Rationale is that instance is used to mean a different thing in cloud. Potentially, it just needs more thought on how wcloud interacts with different instances, and if you have access to multiple instances, etc...

Rationale is that instance is used to mean a different thing in cloud.

This was my confusion, because as this stands they do not mean different things. But I guess with #41 they will, so context is fine.

Closed in favour of #41
