Integration tests

[PaulKMueller]

Motivation

Before this PR, a lot of integration tests are not that stringent.
Also, we found that in many scenarios, it can be useful to list environments that should be excluded instead of listing all the environments that should be included in conda-deny license checks.

Changes

This PR makes the integration tests more stringent and adds the CLI flag and config option of exclude-environment which allows for the above described use case.
