[#1770] node: Refactor application configuration
Split all the fields in `cfg` structure on: 1. `applicationConfiguration`; 2. `internals`; // shared entities for an application work, such as `context.Context` 3. `shared`; // holder for the shared entities b/w; 4. `cfgXXX`; // configuration for internal services.
