The ReadOnly and the RunInit keys affect options that have a variable default (configurable in containers.conf). This means we need to handle them a bit differently in quadlet to allow overriding the default. For example, we can't assume ReadOnly=false doesn't need to add any argument because no argument may mean readonly=true if the default is changed. We now don't add any argument (leaving the default) if the key is not specified, or we always add an argument (--foo or --foo=false) if the key is specified (overriding whatever the default is).
