Ticket #502 - setup-ds.pl script should wait if "semanage.trans.LOCK" presen
Bug description: If multiple DSCreate or removeDSInstance run
simultaneously, semanage port fails because only one semanage
transaction is allowed to start.
Fix description: This patch puts "semanage port" in the while
loop and it retries until it succeeds or reaches the max retry
count (in total 5 minutes).
