Add DRA snapshot build (#91018)

* Add support for building against defined build-ids of dependent artifacts
* Introduce DraResolvePlugin and functional tests
* Declare initial dra snapshot ci job for elasticsearch

We run the DRA builds against ubuntu as other release related ci jobs have in the past. Also we only have libs2xmlutills available on our ubuntu based ci workers
