Make POJOs for RethinkDB-specific objects.

[NotJustAnna]

Currently, the query r.table("test").insert(r.hashMap("foo", "bar").run(conn) returns a Map.

But this is the Java driver and we'd have a better interface if we had a POJO, provided by the driver, to unserialize to. This would make the query just barely slightly bigger:

r.table("test").insert(r.hashMap("foo", "bar").run(conn, TableOperation.class)

But this would give automatic completion for all the documented values.

List of known objects:

• [x] CoerceType (coerceTo)
• [ ] Profile
• [ ] Backtrace
• [ ] DbChanges (dbCreate and dbDrop)
• [ ] TableChanges (tableCreate and tableDrop)
• [ ] IndexChanges (indexCreate, indexRename and indexDrop)
• [ ] IndexStatus (indexStatus and indexWait
• [ ] WriteHook (getWriteHook and setWriteHook)
• [ ] TableOperation (insert, update, replace, delete and sync)
• [x] GroupedResult (group)
• [ ] MatchResult (match)
• [x] ~~TimeObject (now, time, epochTime, iso8601, inTimezone, date)~~ Converted to OffsetDateTime
• [ ] TypeOf (typeOf)
• [ ] Info (info)
• [ ] Http (http)
• [ ] Geometry (circle)
• [ ] Polygon (fill, geojson, polygon, polygonSub)
• [ ] Line (line)
• [ ] Point (point)
• [ ] GrantResult (grant)
• [ ] ConfigResult (config)
• [ ] RebalanceResult (rebalance)
• [ ] ReconfigureResult (reconfigure)
• [ ] TableStatus (status)
• [ ] WaitResult (wait)

(Note: these aren't official nor final names)

Would love to see this! Especially handling of "errors"
