INTLY-2830 - Fix webapp logout on os4 clusters

[KevFan]

Motivation

Logout from the webapp is currently broken on OS4 cluster. This pull request fixes this bug allowing logout on OS4 clusters.

Jira:

• https://issues.redhat.com/browse/INTLY-2830

Associated pull requests:

• https://github.com/integr8ly/tutorial-web-app-operator/pull/83
• https://github.com/integr8ly/integreatly-operator/pull/298

What

• The deleteCurrentSessionAuthToken method was modified to return the promise to ensure the OauthAccessToken is deleted before logging out the user.
• In addition, the SSO logout route is now configured to redirect to the root instead of to RHSSO logout as this would fail anyhow with a invalid_indirect errordue to missing client for this (not needed for this)

Verification Steps

OS4

1. Install integreatly
2. Run the webapp locally (point to an OpenShift cluster) or update your webapp deployment to use the image
   • oc edit deployment tutorial-web-app-operator -n rhmi-solution-explorer
   • Change image to quay.io/kevfan/tutorial-web-app-operator:v0.0.42
3. Run the ./scripts/setup-htpass-idp.sh to create sample users
4. Visit solution explorer and sign in / sign out ensuring there are no errors with the sign out Note: There is an known issue where logging out using kubeadmin would sign the user back in. Just testing the users created from the script should be fine

   OS3

5. Edit tutorial web app deployment config and use quay.io/kevfan/tutorial-web-app:2.20.10 as the container image.
6. Ensure user signin and signout still works as expected on an OS3 cluster
