Application wizard: v3 application wizard needs to be able to react to changing connections

The current application wizard for OpenShift v3 takes a project in the constructor. It was designed to be launched from the explorer where a v3 connection/project is selected before the wizard is launched. The wizard is not able to react to changing connections. In order for the wizard to be able to get launched from File->New->OpenShift we need the wizard to be able to react to chaning connections.
