[SPARK-14838][SQL] Skip automatically broadcast a plan when it contains
ObjectProducer
## What changes were proposed in this pull request?
In `SparkStrategies`, `CanBroadcast` will determine whether to broadcast a
plan by the plan's estimated size. For any plan with `ObjectProducer`
interface, its output is a `ObjectType`. As we can't estimate the size of
`ObjectType`, we throw an `UnsupportedOperationException` if trying to do that.
It causes the
[failure](https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/56533/consoleFull).
To fix this, we should skip broadcasting a plan when it contains
`ObjectProducer`.
## How was this patch tested?
Test will added later.
