Andy Adinets b833b642ec Improved multi-node multi-GPU random forests. (#4238)
* Improved multi-node multi-GPU random forests.

- removed rabit::Broadcast() from each invocation of column sampling
- instead, syncing the PRNG seed when a ColumnSampler() object is constructed
- this makes non-trivial column sampling significantly faster in the distributed case
- refactored distributed GPU tests
- added distributed random forests tests
