Redis Add api for functions / eval for ACL check

Something similar to RM_ACLCheckCommandPermissions discussed in #10025

Comment From: yoav-steinberg

@oranagra @YaacovHazan What do you think would be a good response to the API? The way I see it there are 3 possible responses: 1. You have permission. 2. You don't have permission. 3. Invalid command. So should I return an integer? Should I define constants in lua (redis.PERMISSION_OK, redis.PERMISSION_DENIED, redis.PERMISSION_ERR)? Should I return an string: "ok", "denied", "unknown-command"? Should I return a boolean and raise an error in case of an invalid command?

I think returning a boolean and rising an error in case the request is invalid sounds reasonable. i think @MeirShpilraien and @itamarhaber may be in the best place to answer that.

@oranagra I agree, invalid command is an error and should raise an error. The other 2 are the possible responses to a valid input.
