Summary: This diff is a first step towards an iterator based interface for the SearchRadial method which replaces a vector of GeoObjects with an iterator for GeoObjects. This diff works by just wrapping the iterator for the encapsulated vector of GeoObjects. A future diff could extend this approach by defining an interator in terms of the underlying iteration in SearchRadial which would then remove the need to have an in-memory representation for all the matching GeoObjects. Fixes T8421387 Test Plan: The existing tests have been modified to work with the new interface.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it specially suitable for storing multiple terabytes of data in a single database.

See the github wiki for more explanation.
The public interface is in include/. Callers should not include or
rely on the details of any other header files in this package. Those
internal APIs may be changed without warning.
