MutatingAdmissionPolicyBinding binds the MutatingAdmissionPolicy with parametrized resources. MutatingAdmissionPolicyBinding and the optional parameter resource together define how cluster administrators configure policies for clusters.
For a given admission request, each binding will cause its policy to be evaluated N times, where N is 1 for policies/bindings that don't use params, otherwise N is the number of parameters selected by the binding. Each evaluation is constrained by a [runtime cost budget](https://kubernetes.io/docs/reference/using-api/cel/#runtime-cost-budget).
Adding/removing policies, bindings, or params can not affect whether a given (policy, binding, param) combination is within its own CEL budget.

ValidatingAdmissionPolicyBinding binds the ValidatingAdmissionPolicy with paramerized resources. ValidatingAdmissionPolicyBinding and parameter CRDs together define how cluster administrators configure policies for clusters.

The CEL expressions of a policy must have a computed CEL cost below the maximum CEL budget. Each evaluation of the policy is given an independent CEL cost budget.
