Closes rapidsai#2217 The issue identifies some issues if the partitioning ends up with some empty partitions. There were two issues here: 1. The `call_shuffle` method determines whether a graph has weights by comparing the weight pointer to `nullptr`. But if an MNMG partition is empty then the weight pointer will be `nullptr` even if the graph has weights. Added a parameter to identify if the graph is weighted. 2. The `renumber_helper` method was missing an else and was overwriting the correct value with an invalid value if the return from shuffling on a gpu had no entries. These are corrected in the PR.

Partially address rapidsai#2003. 1. Renumber VertexFrontier & SortedUniqueKeyBucket to vertex_frontier_t & sorted_unique_key_bucket_t to be consistent with the naming schemes for graph_t & graph_view_t. 2. vertex_frontier_t to take number of buckets as an input parameter (instead of non-type template parameter) and rename `get_bucket` to `bucket`. 3. Use `constexpr size_t` instead of `enum calss` for bucket indices to avoid unnecessary type casting. 4. Update `fill()` of `edge_partition_src|dst_property_t` to take `handle` instead of `stream` to be consistent with other member functions (e.g. `clear()`) 5. Remove `..._v` primitives that working on a subset of local vertices. 6. Update `v_op` to take vertex ID (to be consistent with `e_op` which takes source & destination IDs). 7. Other miscellaneous clean-ups.

This PR enables MG support for very small datasets where the number of partitions is smaller than the number of workers Dependent on issue rapidsai#2217 to be resolved before merging closes rapidsai#2196 Authors: - Joseph Nke (https://github.com/jnke2016) Approvers: - Rick Ratzel (https://github.com/rlratzel) URL: rapidsai#2216
…raph (rapidsai#2201) This PR adds Single-GPU (SG) Katz Centrality to the pylibcugraph software stack, as well as refactoring SG Katz Centrality for the cugraph software stack. Both Katz Centrality algorithms are wrappers calling a lower level version of the algorithm, originally based on the C API. This PR directly depends on rapidsai#2192, and combined with it, should close rapidsai#1759.
