Adapt to ytt 0.28.0
Ytt 0.28.0 introduced a breaking change. The --output-directory
option was removed. This was done because this option implicitly
emptied the directory, which could be dangerous. While this option
still exist under a different name, the --output-files option is
now recommended.
The installer now uses the --output-files option, but to ensure a
clean installation, it checks, whether the directory already exists
and if it does, asks the user, whether it can empty it. If it is
not allowed to do so, the installation will abort.
