Description of problem:

 The SMCP should be able to set .spec.collector.replicas and .spec.query.replicas in the Jaeger object it creates. 
 When the Jaeger object is modified manually, the changes are lost when a new version of the SMCP is deployed. 

Version-Release number of selected component (if applicable):

 All

How reproducible:

 Always

Steps to Reproduce:

  1.  Modify the Jaeger object, and set .spec.collector.replicas and .spec.query.replicas
  2. Update the SMCP version

Actual results:

 The number of replicas is set back to 1 
  
Expected results:

 The number of replicas remains as defined in the SMCP 

Additional info:

This would help customers to have all the configuration in one place, rather than having to modify the SMCP and the Jaeger object separately.
Alternatively .spec.collector.autoscale, .spec.collector.minReplicas,  and .spec.collector.maxReplicas can be enabled have a dynamic number of replicas for the jaeger collector, and
.spec.query.autoscale, .spec.query.minReplicas, .spec.query.maxReplicas can be enabled have a dynamic number of replicas for the jaeger query
