IBP console: support multizone & storage config

[alxiong]

Currently IBP installation playbook doesn't support multizone openshift cluster & storage config yet.

storage:
  console:
    class: <non-default-storageclass>
    size: 50Gi
clusterdata:
  zones:
    - dal10
    - dal12
    - dal13

Final config could look like:

---
- name: Deploy IBM Blockchain Platform console
  hosts: localhost
  vars:
    state: present
    target: openshift
    arch: amd64
    project: <project>
    image_registry_password: <image_registry_password>
    image_registry_email: <image_registry_email>
    console_domain: <console_domain>
    console_email: <console_email>
    console_default_password: <console_default_password>
    wait_timeout: 3600
    storage:
      console:
        class: my-storage-class
        size: 50Gi 
    clusterdata:
      zones:
        - dal10
        - dal12
        - dal13
  roles:
    - ibm.blockchain_platform.console

@alxiong good spot on zones, will get that added; storage class is already there though: https://ibm-blockchain.github.io/ansible-collection/roles/console.html
