Description of problem:

When configuring firewall for Sat6 on RHEL7 using firewall-cmd, user would presume that adding RH-Satellite-6 service (as indicated by the docs as well) would provide for all the necessary ports for the Satellite to function properly. 
It doesn't.

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

satellite-6.2.0-12.0.el7sat

How reproducible:
 Every time

Steps to Reproduce:
1. Run firewall-cmd --add-servic=RH-Satellite-6
2.
3.

Actual results:

Port for TFTP (udp 69) is not included in the firewall rules. 
Any PXE provisioning will therefore fail. 

Expected results:

All the necessary ports for basic Satellite functions should be included in the RH-Satellite-6 service definition. 

Additional info:

Current service definition:
