A symlink may depend on a directory, but the directory may not
exist yet (and directory runs after symlink). This could be fixed
by changing the priorities, but this could introduce a situation
where a directory depends on a symlink. Instead, all Managers must
ONLY heal their type (ie, symlinks can't do mkdir_p), but there
should be some method to go back and heal things that failed.
After healing, put all failtures in a failture bucket for that
Manager instance, after healing process, start healing again using
just the newest failures, if the number of failures change,
continue to loop the healing process until either 0 errors or the
error count doesn't change.
