TMSS-911: Adaptation of implementation details to match latest changes (shared support primary role, project attributes in Keycloak, etc.)

TMSS-857: Update distinction between successful/failed observations for the reporting (workflow flag)

TMSS-745: fixed inheritance for Meta class in various models. Otherwise base Meta properties (like constraints) are missed.

TMSS-745: pulled out common version number code for templates, and applied it to SchedulingUnitObservingStrategyTemplate as well.

TMSS-745: extract scheduling_constraints_doc and scheduling_constraints_template from submitted template and use it.

TMSS-745: handle trigger submission in one transaction. If anything fails, the whole trigger is discarded.

TMSS-745: use the new functionality from the refactored strategy templates to construct a valid trigger doc, and submit it to tmss

TMSS-745: added various convenience endpoints on the SchedulingUnitObservingStrategyTemplate to get various versions of the template document: plain, complete_with_all_defaults, just_with_the_parameters. Can be used to construct json documents to upload as schedulingunitdraft or for triggers

TMSS-745: added subdict_of_pointer_items method to extract a subdict given a list of json-pointer-paths

TMSS-745: added common trigger template which defines the structure of a trigger submission json doc

TMSS-745: added convenience methods to get either the full template document with all defaults, or with just the items in the parameters list

TMSS-745: set dynamic_scheduling_enabled default True on development environments. Add commissioning projects to current cycle 16

TMSS-876: include Access-Control-Allow-Methods in response headers to hint to the frontend what the user is permitted to do

TMSS-745: added convenience endpoints to fetch valid template documents (with or without all defaults) for any observation strategy template. The user can then inspect that json document to learn, and/or edit some parameters as override, and then upload it as requirements_doc for a new scheduling_unit_draft
