adding no_log: true to avoid leaking redhat_portal_password

[vladi-k]

Without this a malicious user can potentially see redhat_portal_password in clear text in ansible-playbook output or logs

I see that the insights_config module is printing the last valid variable. This should be reported as a bug in the module since anyone using it will encounter this issue.

  hosts: all
  roles:
  - role: redhatinsights.insights-client
    vars:
    - redhat_portal_username: username
    - redhat_portal_password: password
