Support for Redis Sentinel connection for Python library

[anahit42]

Is your feature request related to a problem? Please describe.
We heavily relay on BullMQ as a communication layer between our microservices and we would like to use it in a new service that should be implemented in Python.

I've checked the example from documentation, but seems that it does not support Redis Sentinel connection.

Describe the solution you'd like
Redis Sentinel connection support for python library

Describe alternatives you've considered
Maybe it is possible to provide similar solution as with Node.js, where you could create connection with ioredis, and pass connection itself, instead of connection configs
