generate_systemd: After= and more options

[d-513]

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

/kind feature

Description

According to the generate-systemd manpage, the After= option can be specified to describe dependencies of a container.

According to podman_container docs there is no such option for this in the ansible module.

It would be really useful to have this. For example, I can have a database container and have an app require it to be running

I recently switched to this module's generate_systemd option, and one of my services was unable to connect to a separate postgres container. Even after modifying the unit configuration file to include Requires=db.service and After=db.service I still had issues reconnecting on startup until I added RestartSec=5 to give the database startup some breathing room. 🤷‍♂️

You may consider including the RestartSec option as well. In the meantime, I'll add it with the lineinfile module.

I will add that option to my PR, if Podman generate-systemd has a switch for RestartSec.
