Background

With this PR:
https://github.com/aerogear/ups-test-suite/pull/8

the data-loader can just generate tokens for a given variant.

What

Now, we need to enhance it, that it "collects" all device-tokens and their matching alias metadata (one unique alias per device) into a CVS file.

How

add each installation's token/alias to a cvs file, while registering them with the given variant

Result

A cvs file, containing "devicetoken","alias", so that other software can iterate over the collection for further processing
