Description of problem:

I tried to configure vlan, and I got the following error.


fatal: [192.168.122.215]: FAILED! => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"}, "changed": false, "module_stderr": "Shared connection to 192.168.122.215 closed.\r\n", "module_stdout": "Traceback (most recent call last):\r\n  File \"/root/.ansible/tmp/ansible-tmp-1562572575.7791524-180821907536373/AnsiballZ_nmcli.py\", line 114, in <module>\r\n    _ansiballz_main()\r\n  File \"/root/.ansible/tmp/ansible-tmp-1562572575.7791524-180821907536373/AnsiballZ_nmcli.py\", line 106, in _ansiballz_main\r\n    invoke_module(zipped_mod, temp_path, ANSIBALLZ_PARAMS)\r\n  File \"/root/.ansible/tmp/ansible-tmp-1562572575.7791524-180821907536373/AnsiballZ_nmcli.py\", line 49, in invoke_module\r\n    imp.load_module('__main__', mod, module, MOD_DESC)\r\n  File \"/tmp/ansible_nmcli_payload_qP0vS5/__main__.py\", line 1549, in <module>\r\n  File \"/tmp/ansible_nmcli_payload_qP0vS5/__main__.py\", line 1527, in main\r\n  File \"/tmp/ansible_nmcli_payload_qP0vS5/__main__.py\", line 1425, in modify_connection\r\n  File \"/tmp/ansible_nmcli_payload_qP0vS5/__main__.py\", line 682, in execute_command\r\n  File \"/tmp/ansible_nmcli_payload_qP0vS5/ansible_nmcli_payload.zip/ansible/module_utils/basic.py\", line 2477, in run_command\r\n  File \"/usr/lib64/python2.7/posixpath.py\", line 293, in expandvars\r\n    if '$' not in path:\r\nTypeError: argument of type 'int' is not iterable\r\n", "msg": "MODULE FAILURE\nSee stdout/stderr for the exact error", "rc": 1}


$ cat vlan_test1.yaml
- hosts: targets
  gather_facts: no
  remote_user: root
  tasks:
  - name: Add Vlan 120
    nmcli:
      type: vlan
      conn_name: vlan120-eth1
      vlanid: 120
      vlandev: eth1
      ip4: 192.168.140.100/24
      state: present

The root cause is because vlanid was added into command args array as integer.
vlanid is the integer type. It should be changed into a string to make the command args array. The following is my proposed patch.
