docs: Create an instance of an {@link ISonarExtractor} type.
  
  @param hostURL The host URL pointing to SonarQube.
  @param userName The user name.
  @param password The password for the given user. Beware that it will not be handled in a safe way. So better use a kind of
  technical user or, if possible, use {@link #getExtractor(String)} which does not require any credentials.
  @return A <b>new</b> instance of {@link ISonarExtractor}.
