Add restart: always to all containers

[ar0dd]

Is your feature request related to a problem? Please describe.

The problem right now is that if you restart the host running the containers, the kibana and elasticsearch containers will need to be manually restarted.

Proposed Solution

Right now, restart: always clause is only applied to the fleet-server container. I'd like to propose all major containers restart automatically so the user doesn't have to worry about it.

Thanks!
