Introduce config as code support

[FernandoRojo]

Introduces the ability to use code files in source to set config settings.

As an MVP, supports a yaml file ComponentDetection.yml that can store a variables dictionary

Ex

variables:
  key: "value"

The values in these config files are ordered in priority:

1. Any config file set as the environment variable ComponentDetection.ComponentDetectionConfigFile
2. Any config file passed as an argument: --ComponentDetectionConfigFile
3. Any ComponentDetection.yml file present in the root directory being scanned.
