[Core] Fix docker in image_id

[Michaelvll]

Fixes issue introduced in #3436, as some cloud's default images do not have /etc/docker/daemon.json by default, which causes the following error, during initializing docker image

E 04-25 19:02:45 subprocess_utils.py:84] jq: error: Could not open file /etc/docker/daemon.json: No such file or directory
E 04-25 19:02:45 subprocess_utils.py:84] Job for docker.service failed because the control process exited with error code.
E 04-25 19:02:45 subprocess_utils.py:84] See "systemctl status docker.service" and "journalctl -xe" for details.
E 04-25 19:02:45 subprocess_utils.py:84] 
E 04-25 19:02:54 subprocess_utils.py:84] Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Thanks for identifying and fixing this @Michaelvll ! Left some comments.

Should we fix that for node providers as well?

skypilot/sky/skylet/providers/command_runner.py

Lines 236 to 241 in 8a18133

	self.run(
	'sudo jq \'.["exec-opts"] = ["native.cgroupdriver=cgroupfs"]\' '
	'/etc/docker/daemon.json > /tmp/daemon.json;'
	'sudo mv /tmp/daemon.json /etc/docker/daemon.json;'
	'sudo systemctl restart docker',
	run_env='host')

Why is this fix does not works for k8s?

[Michaelvll]

This is unrelated to the test_docker_preinstalled_package for k8s. That one is probably because we did not install the required packages in the docker container.

Thanks for the quick fix! LGTM.
