@alexbarghi-nv discovered issue with creating graphs through the C API with double weights.

Added CAPI SSSP test which demonstrates the error.  Added fix to the error in the graph creation logic (both SG and MG).

This PR:

1.  Adds Eigenvector Centrality to the pylibcugraph and cugraph software stacks, which started from rapidsai#2180 and is followed up by future PRs in order to close rapidsai#2146  
2. Minor improvements to pylibcugraph Katz Centrality
3. Added functionality to `test_doctests.py` so that certain docstrings can be skipped on different architecture configs (such as ktruss in CUDA 11.4) 
4. Added undirected/directed versions of graph example used in C tests in `datasets`
5. Removed cugraph copy of warning wrapper from pylibcugraph and have it call the pylibcugraph version
6. Testing for both Python eigenvector centrality wrappers

This PR is identical to rapidsai#2243, just that the name of the branch is different

Corrects the BFS docstring by clarifying that multiple start vertices are accepted as long as they are from different components, and that passing start vertices from the same component will result in undefined behavior.

This PR:
1. Refactors SG `hits` with the updated pylibcugraph implementation
2. Refactors MG `katz_centrality` with the updated pylibcugraph implementation, adding support for multiple arguments 
3. Improves support within `test_doctests.py` to ignore certain docstring examples based on the build architecture (such as ktruss in CUDA 11.4)
4. Passing MG `katz_centrality` testing
