Description of problem:

Not having any option to add a description for a port added via "firewall-cmd" command.

Tried to add the description by manually editing the files, but it's getting overwritten while we add the next rule via "firewall-cmd" command.

This specific request is for adding multiple with a proper description for each of them, which was there in IPtables.

Version-Release number of selected component (if applicable):

# cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 7.4 (Maipo)

Booted Kernel: 3.10.0-693.11.6.el7.x86_64

# rpm -qa  firewalld
firewalld-0.4.4.4-6.el7.noarch

How reproducible:

There are no options available to set the "description" together with the command to add port.

Steps to Reproduce:
1. Add the port with "--set-description" option:

==========================================================
# firewall-cmd --permanent --set-description="needed for OSI application" --add-port=3348/tcp
success

# cat /etc/firewalld/zones/public.xml
<?xml version="1.0" encoding="utf-8"?>
<zone>
  <short>Public</short>
  <service name="ssh"/>
  <service name="dhcpv6-client"/>
  <port protocol="tcp" port="3348"/> <<-----
</zone>
==========================================================

Port got added to the "public.xml" file but there are no descriptions.


2. Tried to add the description manually to the configuration file:

======================================================
# cat /etc/firewalld/zones/public.xml
<?xml version="1.0" encoding="utf-8"?>
<zone>
  <short>Public</short>
  <description>For use in public areas. You do not trust the other computers on networks to not harm your computer. Only selected incoming connections are accepted.</description>
  <service name="ssh"/>
  <service name="dhcpv6-client"/>
  <port protocol="tcp" port="3523"/> # needed for OSI application <<<---------
</zone>


 # firewall-cmd --permanent --add-port=3344/tcp
success


 # cat /etc/firewalld/zones/public.xml
<?xml version="1.0" encoding="utf-8"?>
<zone>
  <short>Public</short>
  <description>For use in public areas. You do not trust the other computers on networks to not harm your computer. Only selected incoming connections are accepted.</description>
  <service name="ssh"/>
  <service name="dhcpv6-client"/>
  <port protocol="tcp" port="3523"/>
  <port protocol="tcp" port="3344"/>
</zone>
======================================================


Actual results:

There is no description being set for any of the ports with "--set-description" option.


Expected results:

There should be some option to set a description for each port as per the user requirement.


Additional info:

We do have the option to set the description for particular service, zones, helper, ipset, icmptype which would be added to the corresponding ".xml" files.
