Service Discovery - Change "Namespace" to "Project"

Background:

In Service Discovery, the user is prompted to specify a Namespace to import an OpenShift service.
However, what the user specifies is an OCP Project.

Goal:
Change the label Namespace for Project (or OpenShift Project) in the Service Discovery window, to adjust to the terminology used by OCP.
