Description of problem:

`deployment/logging-view-plugin` is not created if `visualization` spec is not added in clusterlogging CR when the default log store is lokistack. 

In Logging 5.6, we only need to create clusterlogging CR with below yaml:

apiVersion: logging.openshift.io/v1
kind: ClusterLogging
metadata:
  name: instance
  namespace: openshift-logging
spec:
  collection:
    type: vector
  logStore:
    lokistack:
      name: lokistack-sample
    type: lokistack
  managementState: Managed 

and the `deployment/logging-view-plugin` is created automatically. With the above configuration.

In Logging 5.7, the logging-view-plugin will not be deployed unless we add below lines to clusterlogging CR.

  visualization:
    type: ocp-console

when upgrade logging 5.6 to 5.7.0, logging-view-plugin will not be upgraded, it keeps old version.

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

cluster-logging.v5.7.0

How reproducible:

Always

Steps to Reproduce:

1. deploy logging 5.7 and set default log store to lokistack
2. check pod status

Actual results:

`deployment/logging-view-plugin` is not created.

Expected results:

`deployment/logging-view-plugin` should be created. The behavior is what we have in 5.5 and 5.6.
