ScyllaDB release: version 1.7.2

ScyllaDB has released version 1.7.2, a bugfix update for the ScyllaDB 1.7 stable branch, ensuring backward compatibility and support for rolling upgrades. Users upgrading from version 1.6.x are advised to read the release notes due to changes in some metric names. This release addresses several issues, including the improper closure of Thrift connections, failures in the posix_net_conf.sh script during bonding interface configuration, and performance improvements in repair operations by iterating over subranges. Additionally, it fixes memory leaks linked to User Defined Types (UDTs), errors when dropping keyspaces with nested UDTs, crashes from truncating tables consecutively, blocking of the RPC server by large messages, and the potential for accessing freed memory leading to incorrect results. Other fixes involve resolving segfaults during nodetool cleanup, exceptions thrown by sstabledump when dealing with UDTs, and errors reported by node_exporter when monitoring disk usage metrics. Users are encouraged to report any further issues encountered.
