##### SUMMARY
Setting [openssl_csr](https://docs.ansible.com/ansible/latest/modules/openssl_csr_module.html)'s `version` parameter has no effect in ansible 2.8.4; it always remains the default (1).

##### ISSUE TYPE
- Bug Report

##### COMPONENT NAME
openssl_csr

##### ANSIBLE VERSION
```
ansible 2.8.4
config file = /etc/ansible/ansible.cfg
configured module search path = [u'/home/bilge/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
