Allow removing implicit quadlet systemd dependencies

Browse Source 
Quadlet inserts network-online.target Wants/After dependencies to ensure pulling works.
Those systemd statements cannot be subsequently reset.

In the cases where those dependencies are not wanted, we add a new
configuration item called `DefaultDependencies=` in a new section called
[Quadlet]. This section is shared between different unit types.

This will instruct Quadlet to look for units in this directory instead of the common ones and by
that limit the output to only the units you are debugging.
### Implicit network dependencies
In the case of Container, Image and Build units, Quadlet will add dependencies on the `network-online.target`
by adding `After=` and `Wants=` properties to the unit. This is to ensure that the network is reachable if
an image needs to be pulled.
This behavior can be disabled by adding `DefaultDependencies=false` in the `Quadlet` section.
## Container units [Container]
Container units are named with a `.container` extension and contain a `[Container]` section describing

This is equivalent to the Podman `--variant` option.
## Quadlet section [Quadlet]
Some quadlet specific configuration is shared between different unit types. Those settings
can be configured in the `[Quadlet]` section.
Valid options for `[Quadlet]` are listed below:
| **[Quadlet] options** | **Description** |
|----------------------------|---------------------------------------------------|
| DefaultDependencies=false | Disable implicit network dependencies to the unit |
### `DefaultDependencies=`
Add Quadlet's default network dependencies to the unit (default is `true`).
When set to false, Quadlet will **not** add a dependency (After=, Wants=) to `network-online.target` to the generated unit.
