Cartona caching

[alash3al]

Problem

When you try to run the same query multiple items, redash tries to re-execute it again and again, which isn't a bug, for sure there are use cases for this behavior, but we don't want this for our use case.

Solution

Redash already stores the query result each time a query is executed, so what I'm trying to do here is trying to find a query executed withing env $CARTONA_QUERY_RUNNER_CACHING_WINDOW_MINUTES and then return its result instead of executing it, P.S: setting env $CARTONA_QUERY_RUNNER_CACHING_WINDOW_MINUTES to zero means "disable this feature" which is the default behavior.
