Expected behaviour

Create PodMonitor/ServiceMonitor object for Redis and Sentinel.

Actual behaviour

Prometheus exporters are integrated into the RedisFailover CRD, but they still require PodMonitors or ServiceMonitors.

Proposed solution

Allow creating PodMonitor or ServiceMonitor resources along with exporters. For example:

apiVersion: databases.spotahome.com/v1
kind: RedisFailover
metadata:
  name: redis
spec:
  redis:
    exporter:
      enabled: true
    monitoring:
      podMonitor:
          enabled: true
  sentinel:
    exporter:
      enabled: true
    monitoring:
      podMonitor:
          enabled: true

I'd be happy to draft a PR if you like the idea.
