Move elemental-cli to kairos as a pkg and archive the repo

[jimmykarily]

Plan:

-We will create a new binary called kairos-register which is the only thing the user should ever have to install on their workstation. It’s the binary that will be used to register a node (e.g. using QR code). kairos-agent will become simply kairos with all the subcommands it currently has plus the functionality that will be moved from elemental-cli. Additionally, it’s going to have a new lifecycle subcommand which is going to be what elemental-cli used to be (just the low level functionality). Optionally we could have a check, when the user runs this kairos binary outside a Kairos OS, it should print a warning and wait for confirmation. The elemental-cli code will be moved to a pkg in the kairos repository.

Acceptance Criteria

• kairos-agent becomes kairos
• elemental-cli repo is archived
• new kairos binary has a lifecycle subommand that does what elemental-cli used to do
• The elemental-cli repo tests are now part of the kairos repo and they run when they have to run

[Optional - maybe move to other issues]

• move non-low-level functionality from lifecycle to top level kairos command
• show a warning when kairos binary is executed outside a Kairos OS

I do not remember this, but having it separated would be nicer? Wasnt that the point of trying to extract the sdk stuff so we dont:

• rebuild the whole kairos on sdk changes
• keep OS code and tools code in the same repo
• have everything installed in the OS by luet packages

I think we need to rediscuss this becuase otherwise I dont think its the best way forward.

Blocked by: #1346 (we first extract the kairos-agent to an new repository and then move elemental-cli code there)

No longer blocked!

These are the current elemental-cli commands:

  build-disk   Build a raw recovery image
  build-iso    Build bootable installation media ISOs
  cloud-init   Run cloud-init
  completion   Generate the autocompletion script for the specified shell
  convert-disk converts between a raw disk and a cloud operator disk image (azure,gce)
  help         Help about any command
  install      Elemental installer
  pull-image   Pull remote image to local file
  reset        Reset OS
  run-stage    Run stage from cloud-init
  upgrade      Upgrade the system
  version      Print the version

These are the ones I think belong to the kairos-agent lifecycle command:

  cloud-init   Run cloud-init
  install      Elemental installer
  pull-image   Pull remote image to local file
  reset        Reset OS
  run-stage    Run stage from cloud-init
  upgrade      Upgrade the system

@Itxaka do you agree?

[Itxaka]

@jimmykarily agreed. In fact cloud-init can also be dropped as I don't think it's used anywhere, only the run-stage

Alós there is a PR for this already but needs manual QA

[jimmykarily]

Thanks @Itxaka, I linked the issue with the PR now. Please remember to update issues when you work on them to avoid other people working on the same things.

[Itxaka]

Sorry! Was gonna do it tonight but forgot that it's a local holiday and you folks are working 😂

libs merged, needs maybe the pull-image command to be exposed, but install/upgrade/reset are hooked to the old agent commands
