Components should allow resources to be passed as "requires"

Is your feature request related to a problem? Please describe.
Resources should be able to be separated from components and applications. This would allow for better devops control and environmental changes.

Propose a solution
Components should be able to require an resource. This way the resources are not tied to the component. The component can then expect the resource to be provided to them without having to manage the component itself. By using the requires interface, it keeps the integration to components consistent.
