A ConfigSourceProvider will get picked up via the
ServiceLoader mechanism and can be registered by providing a
META-INF/services/org.eclipse.microprofile.config.spi.ConfigSourceProvider file which contains
the fully qualified classname of the custom ConfigSourceProvider.
Iterable<ConfigSource> getConfigSources(ClassLoader forClassLoader)
