Server-side rendering logging abstraction

Based on the initial codebase written by @niieani, Aurelia server rendering will apparently look for `console.debug`.

See https://github.com/aurelia/skeleton-navigation/blob/ssr/skeleton-typescript-webpack-experimental/server/index.ts#L33.

If `console.debug` isn't used by the bootstrapper, we can probably get rid of this and rely upon Aurelia's logger. We should create a new server-based logging implementation (using the aurelia-logging interface), such as `logging-server` or `logging-nodejs` and tie that in to the server rendering pipeline via the injection container.

Start with the referenced server/index.ts bootstrapper and determine whether it relies on console.debug. Then inspect the aurelia-logging interface and the server rendering pipeline to define how a server logging implementation would connect through the injection container. Done means the logging behavior and integration approach are settled and implemented without relying on the bootstrapper's console.debug usage.
