How to allow project admins to use Security Context Constraints

Issue

• Project admins cannot use Security Context Constraints (SCCs) by default.
• A project admin user cannot use SCCs despite having a role which allows them to use SCCs.
• The following error is displayed when the user attempts to assign an SCC:

Error from server (Forbidden): rolebindings.rbac.authorization.k8s.io "system:openshift:scc:anyuid" is forbidden: user "user1" (groups=["system:authenticated:oauth" "system:authenticated"]) is attempting to grant RBAC permissions not currently held:
{APIGroups:["security.openshift.io"], Resources:["securitycontextconstraints"], ResourceNames:["anyuid"], Verbs:["use"]}; resolution errors: [clusterroles.rbac.authorization.k8s.io "anyuid-scc" not found]

• This works if a cluster role is assigned to the same user instead of a role.
