forked from phoenix-oss/llama-stack-mirror
Making a few small naming changes as per feedback: - RAGToolRuntime methods are called `insert` and `query` to keep them more general - The tool names are changed to non-namespaced forms `insert_into_memory` and `query_from_memory` - The REST endpoints are more REST-ful
