Support for the S3 REST API

StorageGRID Webscale supports the Simple Storage Service (S3) API, which is implemented as a set of Representational State Transfer (REST) web services. Support for the S3 REST API enables you to connect service-oriented applications developed for S3 web services with on-premises object storage that uses the StorageGRID Webscale system. This requires minimal changes to a client application's current use of S3 REST API calls.
