Following today's PGI session at OGF33, rename 'Submitted' as 'Pending' and 'Delegated' as 'Processing'.

Take into account that the Execution Service may be unable to provide one or both :
- Notifications,
- Output Sandboxes.

2 Use Cases :
- CreateActivity performs minimal validation, quickly returns Jobids (but NO Stage-in information) and goes to 'Submitted:Incoming',
- CreateValidatedActivity performs complete validation, may return Stage-in info
rmation, and goes directly to 'Submitted:Validated', at the expense of response time.

Exclude internal states.
Second level Job states are also mandatory.
Inside the 'Submitted' state : The Execution Service may already allocate resources - Rename 'Waiting' substate as 'Validated' - Add 'Hold' substate.

- Vector operations on Single Jobs do NOT imply Collection Jobs (which are out of scope).
- Any implementation of the PGI Execution Service MUST implement all first level Job states, exactly as described in this document. It MAY implement substates. If these substates correspond to substates described in this document, then these substates MUST be implemented exactly as described in this document.

Write down that 'Cancellation' and 'Failure' can happen in any substate - Mention Time-out inside 'Delegated:Hold'

Scope is Single Jobs only. This excludes Collection Jobs, Parameter Sweep Jobs, DAG Jobs, ...

- Change first level 'Hold' states as second level substates
- Add third level 'Suspended' substates inside 'Hold' substates
- Clearly separate 'Finished', 'Failed' and 'Cancelled' states
- Add an 'Automatic Resubmission' transition to the 'Submitted' state only from the 'Failed' state"

Storage resources which are necessary for Stage-out must be allocated at the beginning of the 'Delegated' state.

To be thoroughly reviewed and criticized.
