Determines whether an S3 bucket exists or not. This is done by: 1. Creating a PreSigned Url for the bucket. To work with Signature V4 only regions, as well as Signature V4-optional regions, we keep the expiry to within the maximum for V4 (which is one week). 2. Making a HEAD request to the Url

Note:

This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginDoesS3BucketExist and EndDoesS3BucketExist.
