Upgrade to Redis 6.0.9 (#487)

This unlocks using the new I/O Threads feature of Redis 6.X.

In order to support it the redis template file now accepts a parameter
allowing an operator to enable it and pick how many threads.

By default sets threads to 1, which disables the feature and acts like
redis 5.
