we can load a union dataframe by doing `loadFromMapRDB("/clients/*/*.table")`

Adding `joinWithMapRDBTable` function (apache#529)

The related documentation of this function is here https://github.com/anicolaspp/MapRDBConnector#joinwithmaprdbtable.

The main idea is that having a dataframe (no matter how was it constructed) we can join it with a MapR-DB table. This functions looks at the join query and load only those records from MapR-DB that will join instead of loading the full table and then join in memory. In other words, we only load what we know will be joint.

Pass through the `imagePullSecrets` option to the k8s pod in order to allow user to access private image registries.

See https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/

Unit tests + manual testing.

Manual testing procedure:
1. Have private image registry.
2. Spark-submit application with no `spark.kubernetes.imagePullSecret` set. Do `kubectl describe pod ...`. See the error message:
```
Error syncing pod, skipping: failed to "StartContainer" for "spark-kubernetes-driver" with ErrImagePull: "rpc error: code = 2 desc = Error: Status 400 trying to pull repository ...: \"{\\n  \\\"errors\\\" : [ {\\n    \\\"status\\\" : 400,\\n    \\\"message\\\" : \\\"Unsupported docker v1 repository request for '...'\\\"\\n  } ]\\n}\""
```
3. Create secret `kubectl create secret docker-registry ...`
4. Spark-submit with `spark.kubernetes.imagePullSecret` set to the new secret. See that deployment was successful.

* [SPARK-20922][CORE] Add whitelist of classes that can be deserialized by the launcher.

Blindly deserializing classes using Java serialization opens the code up to
issues in other libraries, since just deserializing data from a stream may
end up execution code (think readObject()).

Since the launcher protocol is pretty self-contained, there's just a handful
of classes it legitimately needs to deserialize, and they're in just two
packages, so add a filter that throws errors if classes from any other
package show up in the stream.

This also maintains backwards compatibility (the updated launcher code can
still communicate with the backend code in older Spark releases).

Tested with new and existing unit tests.
