directaccess: change rule from opt-in to opt-out
Before this patch we would opt-in commands for direct access and the default
filter for new repository was 'visible'.
With this patch, the default filter for new repos is
'visible-directaccess-warn'. It means that by default all the commands have
directaccess with warnings.
