TMSS-320: changed SIPidentifier to make it lighter in storage and (de)serialization. Changed ForeignKey into OneToOneField, ensuring each SIPIdentifier is used only once. Create new SIPidentifier instances where/when needed by default. Adated scheduling of observation/pipeline subtasks for bulk creation and usage of global_identifiers, and added a schedule_ingest_subtask method.

Added the following flags:
- Ingest_permission_required bool on SU Draft & Blueprint
- ingest_permission_granted_since on SU Blueprint
- auto_ingest on project

When auto_ingest=False, the scheduling units are be created with ingest_permission_required = True

TMSS-190: renamed Setting AUTOSCHEDULE/allow_scheduling_observations to DYNAMIC_SCHEDULING_ENABLED/dynamic_scheduling_enabled. Disabled it by default for TMSS as requested by PO. Enabled it for the test environment if the dynamic scheduler service is started.

TMSS-190: let stoptime be set by client(s) instead of assuming that a state update to finishing should always set the subtaks's stoptime

TMSS-322: reimplemented this feature. As stated in the ticket: such a convenience log_url is not part of the Subtask model, but can be a view on the model. So, implemeted it in the viewset. Now, fetching subtasks from the TMSS db is superfast again.

TMSS-337 Add testcase for checking relative_start/stop_time and observation_end_time using UC1 stategy template

TMSS-337 Remove 'default' value in SchedulingUnitBlueprint and add propertyobserved_end_time in TaskBlueprint

TMSS-334: bug fixes and typos on previous quick performance fix. There are many more optimization opportunities!

TMSS-190: fixed aggregated status. It should be possible to do this in a single select statement, but for now this is ok

TMSS-334: quick performance fix with big speedup in getting taskblueprints and schedulingunitblueprints. There are many more optimization opportunities!

TMSS-324 Add SIPIdentifier table. Add global_sip as foreignkey to the SubTask, Dataproduct and SAP table. Remove identifier from SAP specifications_doc because its in model now.

Changes Updated

TMSS-322 Add log_url to SubTasks. Pipeline will have a link based on RADBID (so subtask needs at least be scheduled). Observation will have a link to cobalt error log based on its subtask id. Also convenient function for scheduling_unit_blueprint added

Moved viewflow from tmssapp to the new workflowapp
