Possibility to add exceptions for yarn audit

[olastor]

Do you want to request a feature or report a bug?

feature

What is the current behavior?
All vulnerabilites are listed with yarn audit

If the current behavior is a bug, please provide the steps to reproduce.

What is the expected behavior?

Having the option to ignore certain security issues. In nsp you could add exceptions by adding a .nsprc file like this one

{
  "exceptions": ["https://nodesecurity.io/advisories/12"]
}

This is in many cases needed if for example a vulnerability does not concern you, but breaks you ci build, because you have yarn audit in it.

Please mention your node.js, yarn and operating system version.
OS: Fedora 28 x86_64
node: v8.12.0
yarn: 1.12.3
