make create directory recursive

[ramonskie]

when you can provide the path
for example
default[:stash][:backup_client][:backup_path] = '/tmp/backups/stash-backup/'
then you should be able to do this this is now not possible
because the recursive options is not set

Thanks @ramonskie

I think the recursive flag is never set to true

Going to add that in.
