/**
 * A stripped-down implementation of [ConfigurationService] which serves two purposes:
 * 1) Injected as an OSGi implementation of [ConfigurationService] for libs which still
 * expect to find a [ConfigurationService] via OSGi
 * 2) Wrapped by [ConfigurationServiceConfigSource] to be used in new config
 *
 * NOTE: this abstract base class exists so that a test implementation can be written
 * which pulls [properties] from somewhere else.
