queue-service's Lua script fails in Redis Cluster due to cross-slot key access

[y-oksaku]

What happened:

When running a Lua script on Redis Cluster, the script fails with the error:

ERR Error running script: Lua script attempted to access a non local key in a cluster node.

Then builds cannot be started.

What you expected to happen:

The Lua script added screwdriver-cd/queue-service#80 should execute on Redis Cluster.

Perhaps, we should use hashtag correctly because the Lua script are not able to access keys of different slots. (Ref)

How to reproduce it:

1. Use Redis in Cluster mode.
2. Start a build
