Ability to run extended module commands on RedisInputBinding

[robertopc1]

Hi @mapalan / @MSFTeegarden !

I know only single output read commands are supported for now. (here)

Adding this one so we can track it.

Feature: Retrieve a JSON document with RedisInputBinding
Scenario: User uses PubSubTrigger to listen to JSON.Set commands
Given The Azure Function triggers
And I have a Redis Input Binding
When I configure the Redis Input Binding to run the command: JSON.SET {Message}
Then I should be able to receive the JSON value(s)/ or document depending on the configuration provided
