@slow,@scripting, 
Return information about the function that's currently running and information about the available execution engines.
The reply is map with two keys:
running_script: information about the running script. If there's no in-flight function, the server replies with a nil. Otherwise, this is a map with the following keys:
- name: the name of the function.
 - command: the command and arguments used for invoking the function.
 - duration_ms: the function's runtime duration in milliseconds.
 
engines: this is a map of maps. Each entry in the map represent a single engine. Engine map contains statistics about the engine like number of functions and number of libraries.
You can use this command to inspect the invocation of a long-running function and decide whether kill it with the FUNCTION KILL command.
