To implement CreateRoleAssignment and CreateRoleAssignmentModal (wrapping up CreateRoleAssignment) components.

CreateRoleAssignment contains the properties

• roles: Role[]
• clusters: Cluster[]
• getNamespaces: (clusters: Cluster[]) => Namespace[]
• onCancel: () => void
• onSave: (roleAssignment: RoleAssignment) => void

get RoleAssignment YAML schema from already existing AccessControl (or Overview) schema.json

Create Role Assignment component could depend on a context, meaning the modal could be open from specific User, Group, Cluster, ClusterSet or Role. If any of those entities is sent as a part of the component properties the field will be hidden and the title will be adapted accordingly
