This PR is to integrate the Vertex Standalone API for Check Grounding.
The check grounding API determines how grounded a given piece of text is in a given set of reference texts. The API can generate supporting citations from the reference text to indicate where the given text is supported by the reference texts.
This is implemented as a output parser as Check Grounding is usually done once the generation step of the RAG pipeline is done.
