No 'current' symlink for $SNAP_USER_DATA

[Stuart Bishop]

There is a 'current' to the current $SNAP_DATA which is very useful (/var/snap/mysnap/current -> /var/snap/mysnap/42), as that path can be used to add or edit contained datafiles from outside containment, without worrying about too much about snap updates happening simultaneously and changing the paths.

There is no equivalent for $SNAP_USER_DATA. Can we have one please?

This is a particular problem if you need absolute paths to any data files. I've just needed to workaround this issue by using $SNAP_USER_COMMON and requiring manual cleanup if the snap gets reverted, because I need to store absolute paths to files in the applications configuration.
