ScyllaDB release: version 1.1.3

ScyllaDB 1.1.3, a bugfix release of the ScyllaDB 1.1 stable branch, ensures backward compatibility and supports rolling upgrades, addressing several key issues. The update resolves problems such as inefficient SSTable sharing across shards during migration, ungraceful shutdowns when nodes run out of disk space, cache invalidation issues with nodetool refresh, and stale data retrieval during concurrent reads and table operations. The fixes included in this release are also part of the stable 1.2.1 release, and users are encouraged to upgrade to the 1.2 series for enhanced stability and performance. Contributions from multiple developers, such as Asias He, Avi Kivity, Nadav Har 'El, Pekka Enberg, Raphael S. Carvalho, and Tomasz Grabiec, have improved aspects like logging, error handling, and read consistency.
