[bug] Automated Graph Update for ArangoDB Backend on Collection Addition

[kanchan-dhamane]

Describe the bug
During the initialization of the GraphQL setup in GUAC, the graphql connects to ArangoDB and checks for the existence of a graph. If a graph is present, the setup skips creation of new graph. However, when a new collection is added in code, and the graph already exists, it does not update graph to accommodate the new collection.

To Reproduce

1. Use 0.3.0 version GraphQL image to setup GraphQL a ArangoDB
2. Update the GraphQL deployment to use 0.4.0 version GraphQL image
3. Try ingesting data in using gucone collect files command

Expected behavior
Update a graph, whenever a new collection is added via code.
