Summary:
ToString() is created as some platform doesn't support std::to_string(). However, we've already used std::to_string() by mistake for 16 months (in db/db_info_dumper.cc). This commit just remove ToString().

Summary:
Use `unique_ptr<DB>` to make sure the DB object is deleted. Previously it was not, which led to accumulating file descriptors for deleted directories because a `DBImpl::db_dir_` from each test remained alive.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/9939
Test Plan: run `lsof -p $(pidof db_basic_bench)` while benchmark runs; verify no FDs for deleted directories.

Summary:
I tried evaluating https://github.com/facebook/rocksdb/issues/9611 using DBGet microbenchmarks but mostly found the change is well within the noise even for hundreds of repetitions; meanwhile, the InternalKeyComparator CPU it saves is 1-2% according to perf so it should be measurable. In this PR I tried adding a mmap mode that will bypass compression/checksum/block cache/file read to focus more on the block lookup paths, and also increased the Get() count.

Summary:
DBGet p95 and p99 have high variation, remove them for now.
Also increase the iteration to 3 to avoid false positive.

Summary:
Some changes to make it easier to make FilterPolicy
customizable. Especially, create distinct classes for the different
testing-only and user-facing built-in FilterPolicy modes.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/9567
Test Plan:
tests updated, with no intended difference in functionality
tested. No difference in test performance seen as a result of moving to
string-based filter type configuration.

Summary:
* Add more micro-benchmark tests
* Expose an API in DBImpl for waiting for compactions (still not visible to the user)
* Add argument name for ribbon_bench
* remove benchmark run from CI, as it runs too long.

Summary:
Directory fsync might be expensive on btrfs and it may not be needed.
Here are 4 directory fsync cases:
1. creating a new file: dir-fsync is not needed on btrfs, as long as the
new file itself is synced.
2. renaming a file: dir-fsync is not needed if the renamed file is
synced. So an API `FsyncAfterFileRename(filename, ...)` is provided
to sync the file on btrfs. By default, it just calls dir-fsync.
3. deleting files: dir-fsync is forced by set
`IOOptions.force_dir_fsync = true`
4. renaming multiple files (like backup and checkpoint): dir-fsync is
forced, the same as above.

Summary:
Add google benchmark for microbench.
Add ribbon_bench for benchmark ribbon filter vs. other filters.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/8493
Test Plan:
added test to CI
To run the benchmark on devhost:
Install benchmark: `$ sudo dnf install google-benchmark-devel`
Build and run:
`$ ROCKSDB_NO_FBCODE=1 DEBUG_LEVEL=0 make microbench`
or with cmake:
`$ mkdir build && cd build && cmake .. -DCMAKE_BUILD_TYPE=Release -DWITH_BENCHMARK=1 && make microbench`
