ERP5Generator: new 'id-store-interval' parameter to configure mysql_non_continuous_increasing

Because it is mainly used from the 'initsite' zope.conf section, the passed
value is often a string, hence the automatic cast to integer.

The default is defined in erp5_core: 1
The specific value '0' disables storage in ZODB.
Another other value sets the interval.
