Description of problem:
When osad looses the connection to jabberd, it stops running.

Version-Release number of selected component (if applicable):
Satellite 4.0.6

How reproducible:
always

Steps to Reproduce:
1. Install and start osad on a system registered with the Satellite.
2. Run "service jabberd restart" on the Satellite server.
3. Run "service osad status" on the Satellite client.
  
Actual results:
The osad process dies, administrators loose the Push to Client functionality
until they manually restart the osad service on all clients.

Expected results:
osad should continue running, and wait for the Jabber server to come back.

Additional info:
Currently, we install a crontab entry to periodically check if osad is still
running, and run "services osad restart" if it is not.
