We might want to enable the PodTolerationRestriction admission controller to be able to restrict what tolerations pods in certain namespaces should be able to use.

This might be useful if platform admins need to have isolated nodes for specific workloads and to restrict such that application developers don't (by mistake or on purpose) set tolerations such that it interferes with the other workload.

Describe the solution you'd like A clear and concise description of what you want to happen.

Enable the admission controller so we are able to set up such restrictions.

Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered.

Not enabling this.
