Feature Request

Description of problem:
When we create a rich rule, the only way to manipulate them is by writing the whole rich rule. 
For example, we have a rule that allows connection to port 3128 for a specific IP.
If we want to check for it's presence we need to search for the specific rule. 
Removing the rule again requires to write the complete rich rule. 

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

How reproducible:
firewall-cmd --add-rich-rule='rule family=ipv4 source address=192.168.1.18 port protocol=tcp port=3128 accept'

Actual results:
To remove the rule we need to write the rule again. 

Expected results:


What I propose is to add an extra argument, name or id. 
So, the command will be 
firewall-cmd --add-rich-rule='name=proxy-28 rule family=ipv4 source address=192.168.1.18 port protocol=tcp port=3128 accept'

Then, we would remove the rich rule using the name instead of the whole rule.
