Bug 617013 - repl-monitor.pl use cpu upto 90%

Resolves: bug 617013
Bug Description: repl-monitor.pl use cpu upto 90%
Reviewed by: nhosoi (Thanks!)
Branch: master
Fix Description: The script recursively looks for servers - looks at servers
in replication agreements, adds them, then looks for replication agreements
on those servers, etc.  When it added the servers, the logic was faulty for
seeing if the server was already in the list.  So it just kept recursing
forever.  One of the problems was that the script did not like a hostname
with a non \w char in it, such as the "-" char.  There was another problem
with matching a server without a shadowport.
Platforms tested: RHEL5 x86_64
Flag Day: no
Doc impact: no
