When adding datasource fails from CLI, created Datasource ID should be printed

[rlaager]

Feature Request

In a local script, we are calling e.g. /usr/share/cacti/cli/add_datasource.php --host-id=261 --data-template-id=90. It does not print out the ID of the DS created. We need the ID for further steps.

Describe the solution you'd like

I would like it to print $local_data_id in some form.

Describe alternatives you've considered

We have considered doing all the work of add_datasource.php in our script. That would be a lot of duplicated effort.
