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):

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

Booted Kernel: 3.10.0-693.11.6.el7.x86_64

1. 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:

==========================================================

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

1. 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:

======================================================

1. 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>

1. firewall-cmd --permanent --add-port=3344/tcp
   success

1. 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.
