only download ziti CLI because it has everything now

[qrkourier]

The downloader/installer role was written back when ziti-controller was a separate binary, but now ziti controller is built in to the main ziti CLI.

Change the role to only download/install the ziti CLI.

[qrkourier]

Now the ziti CLI is available as an rpm, deb package for Linux, so the role should use that.
