[Service] Make it possible to use non-auto sizes for volumes with adjust_by_ram (#1111)

## Problem

In Agama a volume can have automatic sizes based on one or several of
the following reasons:

- Snapshots
- Fallbacks from other volumes (eg. "/" max size can exist or not based
on the existence of "/home")
- Size of the RAM

But the third one was not working because it was impossible to set the
sizes manually for volumes with the property `adjust_by_ram` in their
corresponding outline.

## Solution

This sets the new YaST setting `ignore_adjust_by_ram` if the user has
decided to manually enforce sizes. So now it's possible to honor the
automatic size or to use custom sizes instead.

To get some background on how this functionality compares to the
traditional YaST checkbox "Enlarge to RAM Size for Suspend", see the
dedicated section at the description of
https://github.com/openSUSE/agama/pull/1081.

Additionally, this pull request enables `adjust_by_ram` for swap at the
Tumbleweed product, to raise awareness and get feedback.

## Testing

- Added a new unit test
- Tested manually (see screenshots above)
