Summary:
Add a command in ldb so that users can print out tombstones in SST files.
In order to test the code, change the interface of LDBCommandRunner::RunCommand() so that it doesn't return from the program, but return the status code.

Summary:
We add two subcommands `write_extern_sst` and `ingest_extern_sst` to ldb. This PR avoids changing existing code because we hope to cherry-pick to earlier releases to support compatibility check for external SST file ingestion.

Summary:
Currently dump_wal cannot print the prepared records from the WAL that is generated by WRITE_PREPARED write policy since the default reaction of the handler is to return NotSupported if markers of WRITE_PREPARED are encountered. This patch enables the admin to pass --write_committed=false option, which will be accordingly passed to the handler. Note that DBFileDumperCommand and DBDumperCommand are still not updated by this patch but firstly they are not urgent and secondly we need to revise this approach later when we also add WRITE_UNPREPARED markers so I leave it for future work.
Tested by running it on a WAL generated by WRITE_PREPARED:
$ ./ldb dump_wal --walfile=/dev/shm/dbbench/000003.log | grep BEGIN_PREARE | head -1
1,2,70,0,BEGIN_PREARE
$ ./ldb dump_wal --walfile=/dev/shm/dbbench/000003.log --write_committed=false | grep BEGIN_PREARE | head -1
1,2,70,0,BEGIN_PREARE PUT(0) : 0x30303031313330313938 PUT(0) : 0x30303032353732313935 END_PREPARE(0x74786E31313535383434323738303738363938313335312D30)

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/

Summary: add backup support for ldb tool, and use it to run load test for backup on two HDFS envs
Test Plan: first generate some db, then compile against load test in fbcode, run load_test --db=<db path> backup --backup_env_uri=<URI of backup env> --backup_dir=<backup directory> --num_threads=<number of thread>
