Retry nmcli command when timeout reached

From time to time, Ansible is raising error:

    TASK [Ensure crc knows about its second NIC]
    crc | ERROR
    crc | {
    crc |   "msg": "Error: Failed to modify connection 'ci-private-network': Timeout was reached\n",
    crc |   "name": "ci-private-network",
    crc |   "rc": 1
    crc | }

Add retry parameter to avoid CI job to fail.
