Allow orders to be added to a block instruction in a workflow

Current Situation

• With JS-1971 users can specify a start position for an order in a workflow. However, the start position is limited to
  • top level instructions, i.e. the first hierarchy level of instructions in a workflow
  • branches of an If Instruction.

Desired Behavior

• Adding Orders
  • Users want to add orders to a specific block instruction in a later hierarchy level, for example to a specific branch of a Fork Instruction, a Lock Instruction etc. To this purpose the block can be specified when adding an order.
• Termination
  • Orders added to a block instruction will terminate and will leave the workflow when reaching the end of the block.
• Start Position / End Positions
  • Orders can be added to any start position in a block and can be caused to terminate with any later instruction before the end of a block.
• Scope
  • When adding orders to a position directly in a block instruction such as Lock Instruction, ConsumeNotices Instruction etc. then the conditions of the instruction (locks, notices) will not be considered.
  • Orders that fail and that are subject to an outer Retry Instruction or Try-Catch Instruction will be handled by the respective instruction.
