Swagger is not acessible for Che without oauth

[Katka92]

Describe the bug

I've deployed Che without OAuth and I'm not able to access the swagger page. I see the page for a while, but after a few seconds, an error screen is shown.

Che version

• latest
• nightly
• other: please specify

Steps to reproduce

1. Deploy Che using chectl : checlt server:start -n katka-che --installer=operator --platform=openshift
2. Change the CheCluster yaml - set openShiftoAuth to false
3. Allow user creation in keycloak
4. Create new user
5. Access swagger: /swagger
6. Wait for a few seconds for the error page to appear

Expected behavior

Swagger should be accessible.

I've added label "area/wsmaster", because swagger is exposing wsmaster API. If you thinkg some other arrea is more appropriate, please change that. Thanks (I have no idea whose responsibility swagger should be 😄 )

I believe it's caused by eclipse-che/che-operator#491
@tolusha Could you take a look and add swagger as a trusted redirect URL as well?

@sleshchenko
yes, I confirm.
