enhancement: tool should return non-zero return code if vulnerabilities found

[mcallaghan-bsm]

A suggestion/enhancement! it would be great (for CI / gitlab / etc) - if ANY vulnerabilities are found, the tool returns non-zero

consider:

$ dotnet-ossindex (params) ./FooMySolution.sln

...
  10 project(s) found

  No packages affected

  No packages affected

etc

$ echo $?
0

but ... if we find vulnerabilities

$ dotnet-ossindex (params) ./FooMySolution.sln

...
  10 project(s) found

  No packages affected

  1 package(s) affected

          Package: pkg:nuget/jQuery@3.3.0
        Reference: https://ossindex.sonatype.org/component/pkg:nuget/jQuery@3.3.0
  Vulnerabilities: - MEDIUM   [CVE-2019-11358]  Improper Neutralization of Input During Web Page Generation ("Cross-site Scripting")
                   - MEDIUM   CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

etc

$ echo $?
0

suggestion is that the tool returns a non-zero return code if ANY vulnerabilities are found;
(certainly up for debate or configuration if the user wants to filter or exclude certain severity?)
