Scope of the changes: - updated example modules to reference Valkey vs Redis in variable names - updated tests to use valkeymodule.h - updated vars in tests/modules to use valkey vs redis in variable names Summary of the testing: - ran make for all modules, loaded them into valkey-server and tested commands - ran make for test/modules - ran make test for the entire codebase --------- Signed-off-by: Dmitry Polyakovsky <dmitry.polyakovky@oracle.com> Co-authored-by: Dmitry Polyakovsky <dmitry.polyakovky@oracle.com>
