Use NVD API 2.0 to download CVE information (#15102) 
#14888

@getvictor This is ready for review, but keeping as draft as there are
probably many tests that need amending.

I used the new version of the `./tools/nvd/nvdvuln/nvdvuln.go` to
compare the current vulnerabilities found in our dogfood environment
with the vulnerabilities found by the code in this PR and both results
match:
```
go run -race -tags fts5 ./tools/nvd/nvdvuln/nvdvuln.go --debug --db_dir ./local --software_from_url <dogfood URL> --software_from_api_token <API_TOKEN> --sync 2>&1 | tee out.txt
[...]
CVEs found and expected matched!
```

nvdvuln

This tool can be used to reproduce false positive/negative vulnerabilities found by Fleet.

The tool has two modes of operation:

  1. Run vulnerability processing using the NVD dataset on a specific software item. Such software item should be specified to the tool with the fields as stored in Fleet's software MySQL table.
  2. Fetch software from a Fleet instance (and their found vulnerabilities), then, run vulnerability processing on such software and report any differences in CVEs against the Fleet instance. This mode of operation is useful to test new changes to the vulnerability processing.

PS: This tool is only useful on systems and software where the NVD dataset is used to detect vulnerabilities. For instance, this tool should not be used with Microsoft Office applications for macOS because Fleet uses a different dataset to detect vulnerabilities on such applications.

Example Mode 1

go run -tags fts5 ./tools/nvdvuln \
    -software_name Python.app \
    -software_version 3.7.3 \
    -software_source apps \
    -software_bundle_identifier com.apple.python3 \
    -sync \
    -db_dir /tmp/vulndbtest
[...]
CVEs found for Python.app (3.7.3): CVE-2007-4559, CVE-2019-10160, CVE-2019-15903, CVE-2022-0391,

CVE-2020-27619, CVE-2020-26116, CVE-2021-3737, CVE-2022-37454

Example Mode 2

go run -tags fts5 ./tools/nvd/nvdvuln/nvdvuln.go \
    -debug \
    -sync \
    -db_dir /tmp/vulndbtest \
    -software_from_url https://fleet.example.com \
    -software_from_api_token <...>

CPU and memory usage

Requirement: gnuplot (brew install gnuplot)

If set to -debug mode, the nvdvuln tool will sample its CPU and memory usage and store them on a file under the -db_dir. Such data can be visualized with the following command:

./tools/nvd/nvdvuln/gnuplot.sh /path/to/db/directory
