Add ACL support
Browse files Browse the repository at this point in the history
- Update server-acl-init job to create tokens that are partition aware
  when Admin Partitions are enabled.
- server-acl-init creates a partition-token that is used by
  partition-init and server-acl-init in non-default-partitions.
- Update partition-init to use provided partition-token when ACLs are
  enabled.
- Update license-policy to be acl:write when created in a partition.
