Fix: Remove wrong constraint in vnf_package_vnfd

Browse Source 
Currently, vnf_package_vnfd table has a following constraint
in database created by tacker db migration.
This is incorrect, so this patch remove the constraint.

CONSTRAINT `CONSTRAINT_1` CHECK (`deleted` in (0,1))

This is created because `deleted` was boolean before.
`deleted` is varchar(36) now, so db migration change its type
by alter_column method. But this does not remove check constraint.
This patch add drop_constraint to remove the constraint.
