feat: support setting up existing container as devcontainer

[amitds1997]

Closes #782.

[amitds1997]

Let me know if I should add/update any existing tests (suites).

To run DevPod with an existing container, use the following command syntax: devpod up <workspace-name> --source container:<container-id> <other-devpod-options>

<container-id> can be the container ID or the container name. Container ID is preferred since it is unique.
<other-devpod-options> can be any up options except --recreate.

devpod stop and devpod delete behavior

1. For devpod delete, we do not delete the container, since it was not created and launched by DevPod.
2. For devpod stop, we do stop the container since it is now set up as a devcontainer, so it should be okay to stop the container since it can easily be restarted too.

@amitds1997 we have a failing test, could you have a look at that please?

Seems like an issue with pulling docker image (log link). Might this be an intermittent thing? The workflows on the previous commit all passed (including the failing one). Since then, I have only added a comment. So, nothing should break.

Nonetheless, I am trying to reproduce this locally, in case something is amiss. I would go ahead and add an e2e test for launching devpod with a running container.

yeah I thought the same earlier, that's why I re-ran the tests. Let's try again tomorrow, maybe it'll sort itself out 🤷‍♂️

that'd be great!

Hey @pascalbreuninger, when are we planning to send out a release with these changes? Are there going to be more alpha releases? Thanks!

[pascalbreuninger]
