Allow cluster admin to provide default image and/or timeout period for all cluster users

Problem:

There's no way in the UI for the cluster admin to

• change the default timeout period for the Web Terminal for all users
• select an image from an image repository to be used as the default image for the Web Terminal for all users

Goal:

Expose the ability for cluster admins to provide customization for all web terminal users through the UI which is available in wtoctl

Why is it important?

Acceptance criteria:

1. Cluster admin should be able to change the default timeout period for all new instances of the Web Terminal (it won't change settings)
2. Cluster admin should be able to provide a new image as the default image for all new instances of the Web Terminal (it won't change settings)
