feat: pass policy (.snyk) to iac-test via the config file.

This commit adds the policy file to the config file. We use the existing "policy" library to find and load the policy file.
We have decided that we can only have one .snyk file per repo, so even if we scan multiple paths, we will use the current working directory to load the .snyk file from the root of the project.
