DBZ-8061: Provided Service Account instead of managed

[ryanvanhuuksloot]

Adding a potential solution for: https://issues.redhat.com/browse/DBZ-8061

I know this is the way that the operator currently handles PVC, JMX etc. Long term I think it would be better to have ReadOnly Dependents so the reconciliation tree isn't hard to follow.

Tested locally with serviceAccount: default

Name:         <name>-config-view-role-binding
Labels:       <none>
Annotations:  javaoperatorsdk.io/previous: <uuid>
Role:
  Kind:  Role
  Name:  <name>-config-view
Subjects:
  Kind            Name     Namespace
  ----            ----     ---------
  ServiceAccount  default 

Also tested with the traditional managed service account.

Seems good. I will explore the possibility of read-only dependents in the future. However in case of SA it might be an overkill (as we are really only concerned about the existence of the SA).
