Add sentinel password to Redis failover configuration

[vlasebian]

Summary

Add sentinel password to Redis failover configuration.

Changes

• Add a new field, password, to the Redis failover config struct

Testing

1. Start Redis in a Master-Replicas with Sentinel topology (e.g. with docker-compose)
2. Update the stack config to contain the following Redis config:

cache:
  service: redis
  redis:
    password: <redis-password>
    failover:
      enable: true
      addresses: [ "localhost:26379" ]
      master-name: mymaster
      password: "<redis-sentinel-password>"

redis:
  password: <redis-password>
  failover:
    enable: true
    addresses: [ "localhost:26379" ]
    master-name: mymaster
    password: "<redis-sentinel-password>"

events:
  backend: redis
  redis:
    store:
      enable: true
    password: <redis-password>
    failover:
      enable: true
      addresses: [ "localhost:26379" ]
      master-name: mymaster
      password: "<redis-sentinel-password>"

3. Start the stack and open the console.
4. Create an application and an end device. If no redis errors are shown, then the connection was successful
