PP-1006 Provisioning enhancement.

Interface 1: Provisioing multichunk aoe request: provision

Change Control: Stable
Synopsis: Allow submission of jobs having multichunk request with provisionable and non-provisionable subchunks.
Details:
- This enhancement to provisioning, will allow user to submit multichunk job request with aoe.
- Each job subchunk can request at most one aoe. If it requests an aoe, the aoe has to match the aoe of all other subchunks in the select..
- Scheduler can schedule such job request by satisfying resource requirement on both provisionable and non-provisionable node.
- Example:
  - Valid qsub requests:
    - qsub -lselect=1:vnode=vmnode:aoe=sles+1:ncpus=10:foo=2 – /bin/sleep 100
      -- subchunk "1:ncpus=10:foo=2" can be satisfied by a non-provisionable node.
    - qsub -lselect=1:aoe=rhel+1:custom_resource_foo=3 – /bin/sleep 100
      -- custom_resource_foo can be satisfied by a non-provisionable node.
    - qsub -lselect=1:aoe=rhel:foo=2+1:aoe=rhel:foo2=2 – /bin/sleep 100
      -- Both the subchunks might be satisfied by two different or single provisionable node.
  - Invalid qsub requests:
    - qsub -lselect=1:aoe=rhel+1:aoe=sles – /bin/sleep 100
      -- Invalid job request ( two different aoe resource requested)
