Increase OpenShift wizards timeouts

OpenShift takes a lot more time to create applications lately. Where 10 seconds where enough initially, 2 minutes and more are needed since the end of last year. For the user this is kinda annoying: when he's creating a new app in the wizard, he gets the message that we timeouted while waiting for the new application to become ready. He then has to close the wizard, check if the application was created (in the console or in an import wizard). He'll then be able to import the existing application and get the git repo cloned to his local workspace. We can improve this considerably by increasing the timeout to 2 or even 3 minutes. The user would then eventually have to wait for much more time but he'll be able to follow the normal workflow in many more cases.
