Version 2.14 - 22 September 2021

Features

Add the barman-cloud-backup-delete command which allows backups in
cloud storage to be deleted by specifiying either a backup ID or a
retention policy.
Allow backups to be retained beyond any retention policies in force by
introducing the ability to tag existing backups as archival backups
using barman keep and barman-cloud-backup-keep.
Allow the use of SAS authentication tokens created at the restricted
blob container level (instead of the wider storage account level) for
Azure blob storage
Significantly speed up barman restore into an empty directory for
backups that contain hundreds of thousands of files

The backup privileges check will no longer fail if the user lacks
"userepl" permissions and will return better error messages if any
required permissions are missing (#318 and #319)
