[NO ISSUE][CLUS] Add Metadata Cluster Partition

- user model changes: no
- storage format changes: no
- interface changes: yes

Details:
- Add a cluster partition reference to the cluster
  partition in which metadata is stored. This allows
  the initial metadata node to be removed from the
  cluster and another metadata node to be assigned
  to that metadata cluster partition. Initially,
  it is assigned to the first partition of the first
  metadata node.
- Use metadata cluster partition in defining metadata
  datasets file splits instead of the assumption of the
  first partition on the initial metadata node.
