restricted-v2: Added support for restricted-v2 Security Context Constraint profile on OpenShift for new installs.

New features

Recycle bin
- It is now possible to retrieve items such as workflows from a recycle bin after they have been deleted. By default, items remain in the recycle bin for 30 days.
Enforce reset on upload
- Allow Hub administrators to prevent uploading of sensitive data within executed workflows. This feature introduces two new KOTS admin settings. The first setting allows the administrator to define the default value of the "Reset workflow(s) before upload" option in KNIME Analytics Platform. The second option allows them to enforce workflow reset which will disable the previously mentioned checkbox and removes the Upload button from the Hub UI.
Auditing for secret store
- With this release, secret store will provide audit information of secret events e.g. secret creation, editing, deletion and consumption.

Additional changes

New "At full capacity" status for execution contexts
- When every executor in an execution context is busy and can’t accept new jobs—because existing tasks are using up nearly all CPU or memory—the context will now display "At full capacity."
For newly created deployments, the default access role for team members is Manage, so that all team members can edit, share, and delete a deployment. For deployments where this is not desired, the role for team members can be switched to Run & Inspect.
For newly created deployments, the default notification setting is now to send an email to the deployment creator in case the deployment fails during execution.
Added improved navigation for data apps.

Fixed a bug where logging out from Hub did not work correctly.
Fixed a bug where reloading a swapped job changed its swapped at timestamp.
Job initiator is now recorded correctly by instrumentation service for data apps running in team scope mode.
Fixed an issue where MinIO volumes may not be backed up correctly by Velero in version 1.15.0
Corrected Istio image sources to avoid pulling from gcr.io
Fixed misconfigured registry URL in the CoreDNS update job which impacted in-cluster DNS resolution for customers using the internal registry
A new version of the application restore script is now available and must be used when restoring from backups on or after version 1.15.1. Find documentation about the restore script here.

Improvement of the Restrict Execution Context Data App: now allows to set labels that are not allowed for execution on a workflow version. This allows workflow validation for shared execution contexts within a single team on the Hub without affecting workflow versions used by other teams.
