Make it easier to start using RocksDB Summary: This diff is addressing multiple things with a single goal -- to make RocksDB easier to use: * Add some functions to Options that make RocksDB easier to tune. * Add example code for both simple RocksDB and RocksDB with Column Families. * Rewrite our README.md Regarding Options, I took a stab at something we talked about for a long time: * https://www.facebook.com/groups/rocksdb.dev/permalink/563169950448190/ I added functions: * IncreaseParallelism() -- easy, increases the thread pool and max_background_compactions * OptimizeLevelStyleCompaction(memtable_memory_budget) -- the easiest way to optimize rocksdb for less stalls with level style compaction. This is very likely not ideal configuration. Feel free to suggest improvements. I used some of Mark's suggestions from here: https://github.com/facebook/rocksdb/issues/54 * OptimizeUniversalStyleCompaction(memtable_memory_budget) -- optimize for universal compaction. Test Plan: compiled rocksdb. ran examples.

Optimistic Transactions Summary: Optimistic transactions supporting begin/commit/rollback semantics. Currently relies on checking the memtable to determine if there are any collisions at commit time. Not yet implemented would be a way of enuring the memtable has some minimum amount of history so that we won't fail to commit when the memtable is empty. You should probably start with transaction.h to get an overview of what is currently supported. Test Plan: Added a new test, but still need to look into stress testing.

Fix compact_files_example Summary: See task #7983654. The example was triggering an assert in compaction job because the compaction was not marked as manual. With this patch, CompactionPicker::FormCompaction() marks compactions as manual. This patch also fixes a couple of typos, adds optimistic_transaction_example to .gitignore and librocksdb as a dependency for examples. Adding librocksdb as a dependency makes sure that the examples are built with the latest changes in librocksdb.
