/**
* Client to a container. It may only be instantiated through a {@link BlobContainerClientBuilder} or via the method
* {@link BlobServiceAsyncClient#getBlobContainerAsyncClient(String)}. This class does not hold any state about a
* particular blob but is instead a convenient way of sending off appropriate requests to the resource on the service.
* It may also be used to construct URLs to blobs.
*
*
* This client contains operations on a container. Operations on a blob are available on {@link BlobAsyncClient} through
* {@link #getBlobAsyncClient(String)}, and operations on the service are available on {@link BlobServiceAsyncClient}.
*
*
* Please refer to the Azure
* Docs for more information on containers.
*
*
* Note this client is an async client that returns reactive responses from Spring Reactor Core project
* (https://projectreactor.io/). Calling the methods in this client will NOT start the actual network
* operation, until {@code .subscribe()} is called on the reactive response. You can simply convert one of these
* responses to a {@link java.util.concurrent.CompletableFuture} object through {@link Mono#toFuture()}.
