all: add D-Bus property "Flags" for Settings.Connection interface
The D-Bus interface already has a boolean property "Unsaved". While that is nicer too look at (in the API), adding a new flag is very cumbersome, and also has more overhead. For example, it requires extending the D-Bus API, all the way down to libnm. Add a flags argument, that will allow to add future boolean flags easier.
