Description

(the issue added retroactively after the PR was merged for reference)

 

There are some cases (e.g. 1, 2) when job ID needs to be accessed from the user code (function).
Existing workarounds doesn't look clean (reliable).

 

One solution discussed offline is to add Optional<JobID> to the RuntimeContext (the latter already contains some information of the same level, such as subtask index).
