🚀 Make policies with dependencies / relations configurable

[joscheuerer]

Is your feature request related to a problem? Please describe.
For some policies it will be necessary to check if two resources have a relationship, i.e. is a Security Group (SG) with certain settings attached to an Instance?

Describe the solution you'd like
Two checks need to be combined:

1. Does a specific resource A have a certain configuration (SG disallowing access)
2. Does another resource B have the resource A attached to itself (Instance has the SG as attachment)

Describe alternatives you've considered
No possible currently
