• Will probably need to work in pagination

1. const catalogGraphServiceName = {from Config table: CatalogGraphServiceName}
2. use NPM module - izara-shared#graphSharedLib.getVerticesByVertexLabel to pull list of Category vertices:
   1. graphServiceName: catalogGraphServiceName
   2. vertexLabel: NPM module - izara-market-shared#CategoryStandardLib.categoryGraphTag
