This patch fixes the format of vnfdId for VNF package.
ETSI NFV-SOL002/003 does not specify the format of vnfdId, but the
current "vnf package API" can only handle vnfdId in UUID v4 format.
In compliance with ETSI NFV-SOL002/003, this patch fixes "vnf
package API" to handle vnfdId other than UUID v4 format.
And change the vnfdId of the VNF package used in "test_individual_vnfc_mgmt_basic.py" for FT to a format other than
UUID v4 format.
