Handle custom restart policies of containers when generating the unit
files; those should be set on the unit level and removed from ExecStart
flags.

Commit 9ac5267 changed the type of the generated systemd units from
`forking` to `notify`. It further stopped using `--cidfile` and instead
intended systemd to take care of stopping the container, which turned
out to be a bad idea.
Systemd will send the stop/kill signals to conmon which in turn may exit
non-zero, depending on the signal, and ultimately breaking container
cleanup.
Hence, we need to use --cidfile again and let podman stop and remove the
container to make sure that everything's in order.

Change the type of units generated with --new from "forking" to
"notify". This brings Podman closer to systemd and opens up
Podman to a number of use cases (see #5572).
Units generated without --new remain with `type=forking`. I
experimented a bit with adding a `--sdnotify` flag to `podman start` but
it doesn't really work well since we're competing with the default
sdnotify mode set during container creation.

podman generate systemd --new inserts extra idfile arguments. The
generated unit can break when the user did provide their own idfile
arguments as they overwrite the arguments added by generate systemd.
This also happens when a user tries to generate the systemd unit on
a container already create with a --new unit. This should now
create a identical unit. The solution is to remove all user provided
idfile arguments.
This commit also ensures that we do not remove arguments that are part
off the containers entrypoint.

In a systemd unit dollar and percent signs are used for variables. A backslash
is used for escape sequences. If any of these characters are used in the create
command we have to properly escape them so systemd does not try to interpret them.

Make sure that arguments with whitespace are properly quoted so they are
interpreted as one (and not multiple ones) by systemd.
Now `-e tz="america/new york"` will be generated as `-e "tz=america/new york"`.
The quotes are moving but the argument is still correct.

When generating systemd unit for pods, we need to remove certain
pod-related flags from the containers' create commands. Make sure
to account for all the syntax including a single argument with key and
value being split by `=`.

Create a new template for generating a pod unit file. Eventually, this
allows for treating and extending pod and container generation
seprately.
The `--new` flag now also works on pods.
