Add DeleteNotice instruction to workflows

Current Situation

• Notice Boards consume Notices. This is possible for the duration of a Notice's lifetime.
• However, the Notice can be consumed any number of times during its lifetime.
• This is desirable for a number of use cases. For use cases that prefer to delete a notice after execution of some instruction following the ExpectNotices Instruction this is not desired: in addition to having Notices deleted by lifetime it is desired to have Noticed deleted after specific events such as completion of a Job Instruction.

Desired Behavior

• A DeleteNotice Instruction should be available for a workflow to delete the specified Notice.
• The operation to delete a notice is exposed to concurrency of workflow instructions optionally running with a number of Agents. Therefore the DeleteNotice Instruction has to be used
  • within a Block Instruction as explained from JS-2011,
  • after using an ExpectNotices Instruction that indicates the Notice to be consumed and later on to be deleted.

Maintainer Notes

• This issue is dismisses as the functionality becomes available with JS-2011.
• For the purpose of safe transactional behavior a Notice can be deleted only when it is consumed which is why the intended DeleteNotice instruction is replaced by the ConsumeNotices instruction.
