Explorer, Properties: User should be able to see what OpenShift version a connection is

steps:

1. ASSERT: have a connection to an OpenShift 3 and an OpenShift 2 server respectively
2. EXEC: look at the entries in the explorer and in the Properties view

Result:

You have no idea about the versions of the OpenShift servers of the connections that you have. You may only figure out implicitly by the "Domains" displayed in the properties for the OpenShift 2 connection.
