Extracted from #79

New URLs should be used for the following requests:

• Login: api.openshift.io/api/login/authorize -> auth.openshift.io/api/login (path changed!)
• Link accounts: api.openshift.io/api/login/linksession -> auth.openshift.io/api/link/session (path changed!)
• Logout: api.openshift.io/api/logout -> auth.openshift.io/api/logout
• Token refresh: api.openshift.io/api/login/refresh -> auth.openshift.io/api/token/refresh (path changed!)
• User search: api.openshift.io/api/search/users -> auth.openshift.io/api/search/users
• User: api.openshift.io/api/user -> auth.openshift.io/api/user (We still need to do something with tenant service calls here!)
• Users: api.openshift.io/api/users -> auth.openshift.io/api/users
• Collaborators: api.openshift.io/api/spaces/{spaceID}/collaborators -> auth.openshift.io/api/spaces/{spaceID}/collaborators
