(Draft) Add a few instance commands

[dexhorthy]

Outstanding work to make this ready

• pact test for usage of /instances V4 API with customerSelector
• add more k8s info to instances list view

---

Right now you need a customer to make this work, because I couldn't get the appSelector to work with the v4 api. There's a few things we should add, including listing all instances, and a few k8s cluster details we can add in.

Using the -o wide flag will give the following columns:

ID STATUS VERSION VERSIONS-BEHIND VERSION-AGE VERSION-AGE-RELATIVE LAST-CHECKIN TTI-LICENSE TTI-INSTANCE FIRST-SEEN FIRST-READY LICENSE-CREATED LATEST-CHANNEL-RELEASE FULL-ID

instance inspect will show a mini terminal version of the instances page. This is a little goofy but I don't hate it. It gives a good way to test multiple consumers of the backend data.

I held off on this because there was testing infrastructure missing at the time, but if anyone wants to resolve conflics and run with it, they should feel welcome to do so.
