fix(Redis Node): Add support for username auth

[netroy]

Summary

This PR adds support for username auth on Redis and RedisTrigger nodes.

To test this, you can use the following docker-compose snippet to start a redis container to test these nodes with:

services:
  redis-auth:
    image: redis/redis-stack
    container_name: redis-auth
    restart: unless-stopped
    environment:
      REDIS_ARGS: "--requirepass password --user username on >password ~* allcommands --user default off nopass nocommands"
    ports:
      - "8001:8001"
      - "6379:6379"

In general, this looks good 😄 It looks like CodeCoverage is complaining about not being able to test this line. Could you add a utils.redisConnectionTest test? I think checking that setupRedisClient is called with the right credentials should suffice.

[dana-gill]

Just to note as well: I tested this a bit differently from the PR description. Here is what I did:

• Logged into my cloud account of Redis Stack
• Created a new credential on n8n using the connection string from Redis Stack. I didn't explicitly create a user on Redis Stack so my username (which Redis automatically assigned to me) was default
• Successfully tested the Info node using the new credential

My previous credentials also worked without having to change anything ✅

What's the purpose of moving the tests to a __tests__ folder? I feel like it introduces a slightly new way to structure the tests

[dana-gill]

__tests__ make sense :)
