Run Remote - Containers within a Remote - SSH session

[felipecrs]

Despite the documentation explains several ways of working with remote docker hosts for the Remote - Containers extension, none of them is optimal, since it requires additional configuration on at least one of:

• VSCode settings (docker.host)
• The host environment (install docker cli, or configure the env using docker-machine)
• The devcontainer (because of bind mounts, and because SSHFS is not fast enough)

It would be much simpler if the Remote - Containers extension could integrate with Remote - SSH, so it could spawn new devcontainers using the existing tools (docker cli) found in the Remote - SSH current session.

This would be similar to how Remote - WSL and Remote - Containers interoperates.

So, users within a Remote - SSH session could see an option Reopen in Container in the remote options for that session.
