Enable SDK without use of SP

[alexandrosfilios]

This PR enables us to write application without the need for the Service Provider. To this end:

• it removes the mandatory (but unnecessary dependencies from the service provider). Instead, the specific services are injected to the node and the view manager
• it removes the service registrations from the core SDKs (view, fabric, Orion) to the end SDK's (ATSA, CC, etc.)
