Enable using reserved resources for VNF
Currently Tacker doesn't support resource reservation, however in telcom system resource reservation is often needed for VNF stable operation. VNF could be operated under conditions with limited infrastructure resources. In such situation, resource reservation is useful for upcoming scaling-out, maintenance works, disaster recovery.
According to NFV standard, each component in MANO shall support features as below.
* NFVO
* decides if and when a resource reservation is needed
* requests a reservation to VIM
* inform a reservation identifier provided by VIM to VNFM
* VNFM
* requesting reserved resource with reservation identifier
* VIM
* provide resource reservation interface
NFVO part does not concrete enough in NFV standard so installing VNFM part of reservation function at first is good way.
