Is your feature request related to a problem? Please describe.

This is a feature request, workspace settings should be register to settings and setup nav group when nav group enabled. After click the workspace settings, it should show a workspace list page.

Describe the solution you'd like

The workspace list application has already been registered to the OSD core applications. But the nav link status of this workspace list is hidden. We need to change the nav link status to visible, then it will be displayed in the left navigation. To registered to the settings and setup nav group, we need to call core.chrome.navGroup.addNavLinksToGroup with specific nav group and application id.
