Description

When trying to configure a remote redis to be used by mudpi-core inside the mudpi.config, the settings are ignored and it tries to default to a local connection.

Reproduction

1. Setup mudpi-core on host1
2. Setup a redis server on host2
3. Configure mudpi-core to use the redis server on host2
4. Start mudpi-core and see it trying to connect to a local redis on host1

Current Workaround

Editing the hard-coded connection details in variables.py lets you define the connection details
