Fat jar all the thing ?

[ImFlog]

While tinkering on the project I wondered if we could get rid of the buildscript repositories dependencies. Turns out it's possible by using a fat jar.
I did it for the Avro custom plugin (didn't really wanted to expose it in the first place) but left the Confluent plugin out of the jar for now.

I think we could embed it as the new features on the schema registry are not many but I am not sure about the plugin usage.

If no-one disagree with this, I will put the confluent libs in the fat jar and thus provide a better integration experience (just apply the plugin).

NB: One way to mitigate that would be to use the confluent version as my plugin version, this can cause issue if I add features that are not related to confluent in itself.

Changed my mind, will do it for confluent packages too.
