Sub-processes of approval
Added the ability to configure subprocesses with execution parameters for each process state. Specifies the identifier of the negotiation object that will run as a subprocess. This subprocess can be started with default parameters, or you can set values for the subprocess parameters. Several sub-processes can be configured. Subprocesses can only be started manually, with parallel execution. If there were running subprocesses for the process state, then upon exiting this state, all subprocesses will become frozen. No convergence with the main process is realized. Through swagger, you can get the current state of the subprocesses and the allowed subprocesses.
