ScyllaDB release: version 1.7.1

ScyllaDB has released version 1.7.1, a bugfix update to its 1.7 stable branch, which remains backward compatible and supports rolling upgrades. Users upgrading from version 1.6.x are advised to review the 1.7 release notes due to changes in some metrics. This release addresses several bugs, including issues with high memory usage when removing temporary sstables, potential undefined behavior when reading large partitions, delayed purging of expired sstables during compaction, and problems with repair and decommission streams timing out. Additionally, it fixes a failed flush leaving behind sstable file subsets, incorrect disk space reporting by Nodetool, and issues with Java tools failing to load the main class. Other resolved bugs include the sstableloader potentially dropping clustering information and Debian Jessie build failures.
