Percolate status CPE context into vulnerability endpoint.

Fully perform a query to find "related" SBOMs to a vulnerability
via advisory status.

Related is any status other than "not_affected" due to the extreme
amount of noise produced by including that status.

For an example of the current output at the time of this commit
from the /api/v1/vulnerability/{identifier} endpoint, see
