Allow custom invokes to read raw input data when invoked without specific record

[Dergash]

At the moment AbstractResponseService#invokeAction implicitly suggests that custom actions could only be invoked for existing records:

tesler/tesler-core/src/main/java/io/tesler/core/crudma/impl/AbstractResponseService.java

Lines 229 to 254 in 6512494

	public ActionResultDTO<T> invokeAction(BusinessComponent bc, String actionName, DataResponseDTO data) {
	ActionDescription<T> action = getActions().getAction(actionName);
	if (action == null || !action.isAvailable(bc)) {
	throw new BusinessException().addPopup(
	errorMessage("error.action_unavailable", actionName)
	);
	}
	preInvoke(bc, action.withPreActionEvents(bc), data, null);
	T record = null;
	if (nonNull(bc.getId())) {
	// Data is changed and we need to apply these changes
	// Lock must be set here
	if (action.isAutoSaveBefore() && nonNull(data) && data.hasChangedFields()) {
	record = updateEntity(bc, data).getRecord();
	} else {
	// No changes comes,
	// but action requires lock
	if (action.isUpdateRequired() && hasPersister()) {
	loadEntity(bc, data);
	}
	// WARNING! Don't touch cache here!
	// getOne() method may not be invoked
	record = doGetOne(bc);
	}
	}
	return action.invoke(bc, record);

So if custom action called without providing a cursor the data from the request will not be passed into the service.
This doesn't seem right as there are at least valid two scenarios I can think of for invoking custom action without pre-existing record:

1. Creating record with custom action (I suspect that missing access to the request data was the original reason behind why we had to introduce action roles concept). We don't have record id yet but we can receive input data and implement creation logic in service
2. Bulk changes for items: it can be easily implemented with by providing affected records ids and changeset to be processed in service's custom action, if latter had the access to raw input.

So basically the suggestion is to allow the service to handle custom actions input in any way needed.
