Make behavior for empty embeddables configurable [DATAJDBC-374]

[spring-projects-issues]

Jens Schauder opened DATAJDBC-374 and commented

When all attributes of an embeddable are null there are two options we have: 

a) make the embeddable null

b) make the embeddable non-null but all it's attributes.

This should be controlled by an attribute of the @Embedded annotation
