Tomaz Bratanic b3bccabc66 Add option to save/load graph cypher QA (#6219) 
Similar as https://github.com/hwchase17/langchain/pull/5818

Added the functionality to save/load Graph Cypher QA Chain due to a user
reporting the following error

> raise NotImplementedError("Saving not supported for this chain
type.")\nNotImplementedError: Saving not supported for this chain
type.\n'

natural language
