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.

This relaxes the branch name restriction from 20 characters to 45. This is achieved by constructing the preview name based on the first 10 characters of the branch name and then the first 10 characters of the hashed value of the branch name.
All places that (to my knowledge) rely on the preview name has been updated.
