podman: Containers with `--restart=always` policy does not restart services automatically after system reboot.

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind feature

Description Containers with --restart=always policy does not cause services to automatically restart after the system reboot, as it does with Docker.

Steps to reproduce the issue:

1. Create a new container with --restart=always policy

podman run -d --name test-rh83 -p 80:80 --restart=always docker.io/httpd
Trying to pull docker.io/httpd...

podman ps -a
CONTAINER ID  IMAGE                           COMMAND           CREATED             STATUS                 PORTS               NAMES
da1ce8f0ec32  docker.io/library/httpd:latest  httpd-foreground  About a minute ago  Up About a minute ago  0.0.0.0:80->80/tcp  test-rh83

1. Reboot or restart the system/kernel
2. Containers shows in Exited state after system reboot and need automatic start.

podman ps -a
CONTAINER ID  IMAGE                           COMMAND           CREATED         STATUS                         PORTS               NAMES
da1ce8f0ec32  docker.io/library/httpd:latest  httpd-foreground  26 minutes ago  Exited (0) About a minute ago  0.0.0.0:80->80/tcp  test-rh83

Describe the results you received: Podman don’t restart containers after system reboot which were in running state whereas docker does support this after applying --restart=always policy .

Describe the results you expected: I understand that podman is daemonless and rely completely on systemd for system integration. Having this feature in podman in future release will remove systemd dependency.
