Summary:
tools/check_format_compatible.sh will check a newer version of RocksDB can open option files generated by older version releases. In order to achieve that, a new parameter "--try_load_options" is added to ldb. With this parameter set, if option file exists, we load the option file and use it to open the DB. With this opiton set, we can validate option loading logic.

Summary:
- Added a new subcommand, 'ldb restore', that restores from backup
- Made backup_env_uri optional (also for 'ldb backup') because it can use db_env when backup_env isn't provided
Test Plan:
verify backup and restore commands work:
$ ./ldb backup --db=/data/users/andrewkr/rocksdb/db_bench-out/ --num_threads 1 --backup_dir=/data/users/andrewkr/rocksdb/db_bench-out/backup/
$ ./ldb restore --db=/data/users/andrewkr/rocksdb/db_bench-out/restore/ --num_threads 1 --backup_dir=/data/users/andrewkr/rocksdb/db_bench-out/backup/
