[NEW PORT] security/open-vulnerability-cli: CLI to query various online vulnerability sources

The open-vulnerability-cli is a command line utility that can be
used to query various online vulnerability sources such as the NVD
or GHSA. The CLI and docker images can be used to mirror the NVD.

Note that the CLI is called vulnz because open-vulnerability-cli
is cumbersome. vulnz is a spring-boot command line utility built
with picocli.
