[che-auth] It is not possible to logout in nativeUserMode

[sparkoo]

Describe the bug

In new nativeUserMode, it is not possible to logout from the dashboard.

The quick and dirty way to log out is to delete all page data from the browser.

Proposed solution

There is an oauth endpoint that signs out the user. <che-url>/oauth/sign_out (for example on CRC with defaults it's https://che-eclipse-che.apps-crc.testing/oauth/sign_out).

Dashboard should be able to recognize nativeUserMode when there is no keycloak. It can tell by getting 404 response from che-server on request /api/keycloak/settings. It is already doing this request at some point and gets into single-user mode after getting 404. Dashboard single-user mode is so far working fine for native-user.
