Add klaus1982 as contributor for MESOS-3023

[klaus]

Hi team,
 
I'm working on MESOS-3023 (Factoring out the pattern for URL generation), and 
have a fix for it; would you help to add me into contributor list? so I can 
assign it to myself and trigger review process :).
 
My JIRA ID is klaus1982 (kl...@cguru.net)
 
 
Regards,
