##### SUMMARY
When using **comment** parameter with iptables module, it is not positioned as the right-most object in the actual iptables table.
The outcome looks very bad at the moment.

##### ISSUE TYPE
- Cosmetic Bug Report

##### COMPONENT NAME
<!--- Write the short name of the module, plugin, task or feature below, use your best guess if unsure -->
**iptables** module, **comment** parameter

##### ANSIBLE VERSION
<!--- Paste verbatim output from "ansible --version" between quotes -->
```paste below
ansible 2.9.9
  config file = /home/me/project/ansible.cfg
  configured module search path = ['/home/me/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /home/me/vConstruction/lib/python3.6/site-packages/ansible
  executable location = /home/me/vConstruction/bin/ansible
  python version = 3.6.9 (default, Jul 17 2020, 12:50:27) [GCC 8.4.0]
```

##### CONFIGURATION
<!--- Paste verbatim output from "ansible-config dump --only-changed" between quotes -->
```paste below
DEFAULT_CALLBACK_WHITELIST(/home/me/project/ansible.cfg) = ['profile_tasks']
DEFAULT_HOST_LIST(/home/me/project/ansible.cfg) = ['/home/me/project/inventory']
DEPRECATION_WARNINGS(/home/me/project/ansible.cfg) = False
HOST_KEY_CHECKING(/home/me/project/ansible.cfg) = False
```

##### OS / ENVIRONMENT
<!--- Provide all relevant information below, e.g. target OS versions, network device firmware, etc. -->
Host where I use Ansible: Ubuntu 18.04 via WSL 2.
Target VM where the iptables rules are being created: Ubuntu 18.04.

##### STEPS TO REPRODUCE
<!--- Describe exactly how to reproduce the problem, using a minimal test-case -->
It can be reproduced by using the following task and running `iptables -L` on the target machine.
I added the DNS task as well, because this one looks correct, but I'm sure that's just because I don't have **ctstate** specified.

<!--- Paste example playbooks or commands between quotes below -->
```yaml
- name: Create HTTPS rule
  iptables:
    chain: INPUT
    in_interface: eth0
    protocol: tcp
    destination_port: https
    ctstate: NEW
    jump: ACCEPT
    comment: Accept new inbound HTTPS connections to eth0 interface

- name: Create DNS rule
  iptables:
    chain: INPUT
    protocol: udp
    destination_port: domain
    jump: ACCEPT
    comment: Accept inbound DNS connections
```

<!--- HINT: You can paste gist.github.com links for larger files -->

##### EXPECTED RESULTS
<!--- Describe what you expected to happen when running the steps above -->
```bash
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:ssh  ctstate NEW /* Accept new inbound HTTPS connections to eth0 interface */
```
##### ACTUAL RESULTS
<!--- Describe what actually happened. If possible run with extra verbosity (-vvvv) -->

<!--- Paste verbatim command output between quotes -->
```bash
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:https /* Accept new inbound HTTPS connections to eth0 interface */ ctstate NEW
ACCEPT     udp  --  anywhere             anywhere             udp dpt:domain /* Accept inbound DNS connections */
```
