Subject: [PATCH] Add ability to pass system properties/env vars to test
 resources service

This commit adds 2 configuration properties for the test resources service,
making it possible to pass either system properties or environment variables
at startup.

This will be useful in order to configure the logging level of the server.
For example, one can add:

```
micronaut {
   testResources {
      serverSystemProperties.put("logger.levels.io.micronaut", "TRACE")
   }
}
```
