Rework createResource and getLogger APIs

* Replace getResourceFactory() function with a resourceFactory
  property
* Replace getLogger function with a log property passed directly to the
  task/middleware (not using the corresponding -util)

 The new APIs should be provided via the existing helper classes [`taskUtil`](https://sap.github.io/ui5-tooling/api/module-@ui5_builder.tasks.TaskUtil.html) and [`middlewareUtil`](https://sap.github.io/ui5-tooling/api/module-@ui5_server.middleware.MiddlewareUtil.html).
 
 #### New API
-* taskUtil|middlewareUtil.**getLogger(**_optionalModuleNameAppendix_**)**
- * The logger instance will automatically have the name of the custom task or middleware. An optionally provided name will be appended accordingly.
-* taskUtil|middlewareUtil.**getResourceFactory()**.**createResource(**_{...}_**)**
+* New parameter **log**
+ * The provided logger instance will automatically have the name of the custom task or middleware.
+ * Additional sub-loggers can be crated using `log.createSubLogger("name suffix")`
+* taskUtil|middlewareUtil.**resourceFactory.createResource(**_{...}_**)**
  * Creates and returns a `Resource` with an interface signature according to the Specification Version of the extension.
- * This implies a `getResourceFactory()` function which provides Specification Version-dependent access to functions of the [`@ui5/fs/resourceFactory`](https://sap.github.io/ui5-tooling/api/module-@ui5_fs.resourceFactory.html)
