Add redis sentinel-backed failover client

[furkansenharputlu]

It should be enabled by if redis.UniversalOptions.MasterName != "" like in redis.NewUniversalClient() function. It should be implemented and tested for all the following projects:

• Gateway
• Dashboard
• Pump
• MDCB

[buger]

Merged Gateway, now needs updating rest of projects (updated PR description to have checklist)

[maciejwojciechowski]

The problem for the gateway is that it is not merged into release branch. Now, it is solved.

[buger]

@furkansenharputlu what about pump?

[furkansenharputlu]

I will send a PR for pump. Also, I will send small config fixes for all projects.
