Description of problem:
I upgraded Satellite 5.6 ext Oracle to new release 5.8 with oracle and the upgrade finished correct. I didn't find some error, but osa-dispatcher doesn't run (no connect to jabber server).

Interesting point is that old version of jabberd is installed on system.
jabberd-2.2.8-22.el6sat.x86_64

and some configuration files are missing on system.

>> ll /etc/jabberd/c2s.xml
ls: cannot access /etc/jabberd/c2s.xml: No such file or directory

Compose Satellite-5.8-RHEL-6-20161212.n.0-Satellite-x86_64-dvd1.iso contains jabberd-2.2.8-23.el6sat.x86_64.rpm 

When I do following steps then it starts work correct.

## upgrade jabberd to new version of package
>> spacewalk-setup-jabberd 
>> rhn-satellite restart

Version-Release number of selected component (if applicable):
rhn-upgrade-5.8.0.3-1.el6sat.noarch

How reproducible:
always from Sat 5.6 (looks that problem is not from Sat 5.7)

Steps to Reproduce:
1. ./install.pl --disconnected --external-oracle --upgrade
2. spacewalk-schema-upgrade
3. rhn-satellite restart
