Remove uuid method from Generator

[simPod]

What is the reason for this PR?

This method added in #427 is a BC break. I had a Provider with uuid function but this added a new Formatter with name uuid which has a precedence over Providers.

Technically it was not a BC however we understand the issue due to the __call methods.

So we discussing it internally. We have 2 options:

• remove the methods
• ensure the Extension interfaces go final.

I think the first option will be taken where the extension interfaces will be for 2.x
