make rocksdb cmake checks less verbose on repeat * fix FindLZ4 to follow convention (LIBRARIES, not LIBRARY) * remove redundant checks from rocksdb/CMakeLists.txt * put all checks through the same macro that uniformly checks for a package, prints the message, adds definition

RocksDB : Add lookup / compiling with optional compression libraries. This change add WITH_ROCKSDB_{LZ4,BZIP2,ZSTD,snappy} CMake variables that can be set to ON/OFF/AUTO. If variable has default value AUTO, rocksdb links with corresponding compression library. OFF disables compiling/linking with specific compression library, ON forces compiling with it (cmake would throw error if library is not available) Support for ZLIB is added unconditionally, as it is always there.
