Rules can now specify a list of data sources names that they need for
their evaluation. This change ensures that data sources required by
the rule are available when creating the rule.

A similar change is being added in the code path implementing data
source deletion ensuring that a data source is not deleted if there
exist rules depending on it.

This change adds code for the maintenance of references to Data
Sources during the creation or update of rule types.

To keep things simple and limit the amount of added code, the code
path is the same for both create and update, in that it always try to
delete references to data sources even in the case of rule creation,
which is always a noop.
