Bearer integration

[that-jill]

This is a POC for bearer, which is a static scanner for security/privacy vulnerabilities.

While brakeman is Rails-specific, Bearer adds support for vulnerabilities on the language-level and supports the following languages:

1. JavaScript/TypeScript
2. Ruby
3. PHP
4. Java
5. Go
6. Python

This PR aims to prove out bearer's effectiveness in the power-tools repo.
