Following our [internal RFC](https://www.notion.so/gitpod/A-Go-based-CLI-for-interacting-with-Preview-Environments-1834aa90bc104a0b836dd523e22f9e93), the work done in this CLI was to make sure it is easily extendable with new commands and that the architecture makes it easy to test.
It also introduces the first command asked in Milestone 1 of that same RFC. Which makes it possible to install the kube-context of different preview environments.
