3.11 has this issue too
openshift-ansible-3.11.23-1.git.0.19cbe21.el7.noarch

+++ This bug was initially created as a clone of Bug #1632397 +++

Description of problem:

 ASB gets installed during upgrade even though ansible_service_broker_install is set to true. 


Version-Release number of selected component (if applicable):
3.10

How reproducible:
100%

Steps to Reproduce:
1. Install 3.9 cluster with ansible_service_broker_install=false
2. Upgrade to 3.10 with ansible_service_broker_install=false

Actual results:
ASB gets installed 


Expected results:
Skip installing ASB


Additional info:
For upgrades the conditional is used openshift_enable_service_catalog=true, when deciding to install the ASB 

```
   https://github.com/openshift/openshift-ansible/blob/master/playbooks/common/openshift-cluster/upgrades/upgrade_components.yml#L7-L21

  - import_role:
      name: ansible_service_broker
      tasks_from: install.yml
    when:
    - openshift_enable_service_catalog | default(true) | bool
```

For installs the conditional is used looking for ansible_service_broker_install=true.

https://github.com/openshift/openshift-ansible/blob/master/roles/ansible_service_broker/tasks/main.yml

  - include_tasks: install.yml
    when: ansible_service_broker_install | bool

We face the same problem at the update from 3.9 -> 3.9.

`ansible_service_broker_install=false` is in the hosts file but the following command want do uodate ansible broker

ansible-playbook -i /tmp/ose-hosts /usr/share/ansible/openshift-ansible/playbooks/byo/openshift-cluster/upgrades/v3_9/upgrade_control_plane.yml

Looks like there is a pull request which fixes this bug.

https://github.com/openshift/openshift-ansible/pull/9770

Any Idea when this fix will be available on 3.9 rpms?
