     * 
     * A method to configure a remote resource. Configuring a remote resource typically involves
     * creating a default configuration object that can be further configured by a
     * {@link org.testifyproject.annotation.ConfigHandler} method. Please note:
     * 
     * 
     * Implementation of this method should not do any work beyond returning configuration
     * object. It should be stateless and should not perform instantiation of the remote
     * resource as that should be handled in
     * {@link #start(org.testifyproject.TestContext, org.testifyproject.annotation.RemoteResource, java.lang.Object)}
     * method.
     * 
     * 
     * The value of PropertiesReader by default encapsulates {@code .testify.yml} configuration
     * properties. A specific section in {@code .testify.yml} can be specified through
     * {@link RemoteResource#configKey()}.
     * 
     * 
     * The configuration object returned by this method is simply default configuration. It can
     * be updated or replaced with entirely new configuration object by the
     * {@link org.testifyproject.annotation.ConfigHandler} method before it is passed to
     * {@link #start(org.testifyproject.TestContext, org.testifyproject.annotation.RemoteResource, java.lang.Object)}
     * method

     * @param remoteResource test class remote resource annotation
     * @param configReader a configuration properties reader
