v0.3.5

IMPROVEMENTS

• The 'list' command can print latest and penultimate of backup name. Now you can use the output of the 'list' command as parameters for another command.

• The 'delete' command has been added. Now you can remove specific backups from local and s3.

  clickhouse-backup delete local <backup_name>
  clickhouse-backup delete s3 $(clickhouse-backup list s3 penult)
