Error Redirect URI in Ego UI Should be Initialized by the DMS

[b-f-chan]

In Ego UI, there is a field on the application level for an Error Redirect URI.

This field is only used by Ego (not identity providers) to redirect users to the correct error page when an OAUTH error occurs logging into the DMS UI.

Currently, this is not automatically initialized against the DMS UI app by the DMS installer script. The DMS admin has to manually configure this as a post-deployment step.

This configuration should be added to our default Ego initialization steps by the DMS Installer.
