[gpuCI] Auto-merge branch-0.17 to branch-0.18 [skip ci]
Adds the ability to get the length/cost of path from source to destination(s). Closely follows [`networkx.shortest_path_length`](https://networkx.org/documentation/latest/reference/algorithms/generated/networkx.algorithms.shortest_paths.generic.shortest_path_length.html#networkx.algorithms.shortest_paths.generic.shortest_path_length). 


Similarities:
1) Takes an optional target vertex
2) If only source is provided, a `cudf` dataframe is returned with columns: `[vertex, distance]` (similar to `networkx` dictionary return)
3) If source and target are specified the exact length is returned or `sys.float_info.max` if the vertex is not reachable. 


Differences:
1) Requires that source be provided, as apposed to `networkx`
2) Nethod of graph traversal is not an option. 

Fixes:
1) Fixes #806 
2) `sssp` and `cugraph.Graph.has_node` vertex checks. Added support for checking for vertexes that are not apart of the graph. in the past, `TypeError` was raised when doing a comparison check (as apposed to `ValueError`)
