It is still impossible to test CDK 3 on central-ci and so, it is willing to test CDK 3 tools operated from devstudio via usage of proxy system settings on local machines.

Steps to follow:
1. Setup local firewall/network rules to simulate that machine resides in restricted network and requires proxy to utilize CDK3 features. ( create_proxy-test_env.sh )
2. Download/install devstudio
3. Download CDK3 minishift binary and prepare the environemnt (run minishift setup-cdk)
4. ASSERT: Cannot subscribe minishift-rhel image during minishift start, can be done via cli
4. Set env. variable MINISHIFT_HTTP(S)_PROXY
5. Start devstudio, add new Container Development Environement server
6. Start server adapter
7. ASSERT: CDK tools are working properly - CDK started successfully

• rhel-image was subscribed
• docker image pulled
• log into openshift
