Add sample for 2.10.x custom build

[sergiodelgadocastellanos]

Hi,

I've been trying to build a custom Dataflow Server with the 2.10 version, but it doesn't work. I've been changing the dependencies, and the server starts, but the Dashboard is not showing and some of the functionalities aren't working.

Could you please provide a custom build sample with the version 2.10?

Thanks in advance!
