feat: replace ansible.netcommon utils with python3 ipaddress module (#416)

##### SUMMARY

Replace `ansible.netcommon` deprecated ipaddr utils with python
`ipaddress` module. The `ansible.netcommon` collection is no longer
required by the collections. We still use the `ansible.utils`
collections for testing
