ETSI-NFV SOL 001 translation: VNF, Compute

Browse Source 
Currently heat-translator supports translation of TOSCA Simple Profile
for YAML[1] and TOSCA Simple Profile for NFV[2] only.
This commit enables to translation of the follwoing type defined in
ETSI NFV-SOL 001[3].
- tosca.nodes.nfv.VNF
- tosca.nodes.nfv.Vdu.Compute
