CLI: save contexts to be able to easily switch

Let’s say I have a staging and production environment, it’s currently a pain to run a shell in both envs back to back.

It would be priceless to be able to save “favorite” contexts to quickly be able to switch from one to another, and even better if we could pass the saved context as a flag to qovery shell commands

Right now I’m handling it with shell aliases but it would be great for it to be native
