Describe the bug

Resource.Expire() as implemented by #133 causes issues when using Podman as the container management tool.

The issues is that Resource.Expire() will immediately cause the container to enter the "Stopping" state (as can be seen in podman ps -a). Podman then disallows any further exec operations on the container, as that requires the container to be in state "Running" (as seen here: https://github.com/containers/podman/blob/7c9d4a42c54b685a3c47ee2200d2bf3811fb5b03/libpod/container_exec.go#L231-L233).

This makes it impossible to launch further commands in a container after Expire() has been called.

Reproducing the bug

Requires enabling the systemd unit podman.socket and pointing DOCKER_HOST to the socket.

pool, _ := dockertest.NewPool("")
resource, _ := pool.Run("postgres", "16-alpine", []string{
	"POSTGRES_PASSWORD=pass",
	"POSTGRES_USER=user",
})
resource.Expire(300)

// This fails due to the container being in state "Stopping"
exitCode, _ := resource.Exec(
	[]string{
		"psql",
		"-U", "user",
		"-c", "CREATE ROLE \"test@example.com.com\" WITH LOGIN;",
	},
	dockertest.ExecOptions{
		Env:    []string{"PGPASSWORD=pass"},
		StdOut: os.Stdout,
		StdErr: os.Stderr,
	},
)
