CDK is now support proxy servers. We also should make sure OpenShift Tools works fine with proxies too.
If devstudio and cdk are installed using DevSuite installer and user configured proxy server correctly then everything should just work on Eclipse side.
This issue covers:

• testing
• creating all needed (currently missing) automated tests (including reddeer/swt bot Integration Tests)
• fixing any problems we have in OpenShift tooling regarding proxy support.
