The random sampling of IVF methods was reverted (#2144) due to large memory utilization #2141. This PR improves the memory consumption of subsamling: it is O(n_train) where n_train is the size of the subsampled dataset. This PR adds the following new APIs: - random::excess_sampling (todo may just call as sample_without_replacement) - matrix::sample_rows - matrix::gather for host input matrix Authors: - Tamas Bela Feher (https://github.com/tfeher) Approvers: - Artem M.
