Add support for IP address to be parameterized in VNFD template

[vishwanath jayaraman]

Use case: As a service provider, one would want to assign fixed ip addresses for VNF ports defined in the VNFD templates so that they could deploy VNFs containing vNICs with known ip addresses instead of assigning it through DHCP.

With this feature
* VNFD templates should support the property “addresses” under ports definition
• Addresses property values can be hardcoded or parametrized using “get_input” property as a list ([10.1.1.2])
• End user should be able to create VNF instances containing vNICs with the given ip address

Find attached a sample VNFD template and parameter values specified in file that this feature once implemented would work with.
