Nautobot Healthchecks fail with Redis Sentinel if password is required

[nniehoff]

Environment

• Python version: 3.7
• Nautobot version: 1.3

If a password is required for redis + redis sentinel the Nautobot healthcheck fails because the healtcheck code is not passing those values to the redis-py library and therefore failing to connect to redis.

Steps to Reproduce

1. Create redis + sentinel cluster with a password
2. Connect Nautobot

Expected Behavior

Nautobot health checks pass

Observed Behavior

$ nautobot-server health_check
