 * A Java SPI (Service Provider Interface) to allow replacing the default {@link ContextStorage}.

 * context propagation system. For example, the returned {@link ContextStorage} could delegate to
 * methods in

{@code
 * com.linecorp.armeria.common.RequestContext}, {@code
 * io.grpc.context.Context}, or {@code
 * org.eclipse.microprofile.context.ThreadContext}

if you are already using one of those systems in your application. Then you would not have to
 * use methods like {@link Context#wrap(Executor)} and can use your current system instead.
