Contains the spec files which control the rendering of specific vulnerability data records within the vulnerability indexer (not yet built)

At the moment, all of these are legacy NVD override specs where we are completely overriding the product input from the nvd vunnel provider. In future, once the vulnerability-indexer is completed, many of these files will become irrelevant and can just be removed while others will become output specifiers where we are tweaking the generated output of the indexer by adding or removing affected or unaffected products, etc.
