Merge "Remove foreign key which is not supported by code"

Remove foreign key which is not supported by code

The foreign key we fixed in the VNF_RES_CUSTOM_TO_VF_MODULE_CUSTOM
table is blocking distribution of the model.  The insert that's
failing is:

insert into VNF_RES_CUSTOM_TO_VF_MODULE_CUSTOM (
	VNF_RESOURCE_CUST_MODEL_CUSTOMIZATION_UUID,
	VF_MODULE_CUST_MODEL_CUSTOMIZATION_UUID)
	values (?, ?);

The error is: "foreign key constraint fails"
