Add missing fields to Middleware views

The fields were not being shown because the associations were not being
loaded. This fixes this, effectively adding data to those columns:

Middleware Servers:
 - Provider
Middleware Domains:
 - Server
Middleware Deployments:
 - Server
 - Hostname
Middleware Datasources:
 - Server
 - Hostname
Middleware Messagings:
 - Server
