Instead of defining 3-4 parameters, this PR enables using a single DSN to configure the default URL context (for commands mainly):
```
framework:
	router:
		base_uri: 'https://my.host:8443/base-path/'
```

When using parameters directly, one can now set the same absolute URI in the `router.request_context.base_url` parameter, this will provide the same benefit.
