add key/value store (redis or similar)

Suggestion for a way this could be done:

Store the k/v pairs as properties on the root or on the parent folder. If there were a groovy method built in that let you do something as simple as

props.set("object","key","value")

that would work right? I'm asking because of other benefits to having this ability right in Groovy without need for authentication, authorization, or (?) a huge section of code to do an LM API call.
