As an Admin I want to have a possibility to configure an alternative dashboard URL

Is your task related to a problem? Please describe

In order to make Eclipse Che integration more flexible with other projects / products that could come up with their own custom dashboard for CDEs it should be possible to override / or setup redirect for the main Dashboard URL:

 dashboard:
    redirectURL: https://<alternative-dashboard-url>

Once this CR property is set navigating to dashboard would redirect to the alternative dashboard url.

Describe the solution you'd like

Admin can configure alternative User Dashboard URL from the CR

N.B. workspace loader flow as well as the factory # flow should continue working as before.
