Add Location to responses of Create VNF Package

According to SOL005 v3.3.1 Table 9.4.2.3.1-1 [1], the HTTP response
shall include a "Location" HTTP header that contains the resource URI of
the individual VNF package resource.

In order to realize the above, this patch adds a Location header, which
includes a URL of a created VNF Package, to responses for `POST
{apiRoot}/vnfpkgm/{apiMajorVersion}/vnf_packages` requests.

Also, this patch removes unused arguments from methods in ViewBuilder.
