Merge component service oss+cloud

[vigoo]

In this step we take the golem-component-service-base, golem-component-service and cloud-component-service crates and merge into one crate. All the previously existing behaviors (like requiring auth tokens or not) should remain available through configuration. There should be a single gRPC and REST API remaining.

• After this, we no longer have separate clients generated from OpenAPI, this has to be reflected in the CLI
• Auth related code (abstractions, context objects, etc) need to be cleaned up and refactored. This should be done in sync with merging the worker service. (I gave a bigger estimate for that ticket assuming that is done first but the order is not that important)
