[SPARK-24757][SQL] Improving the error message for broadcast timeouts
## What changes were proposed in this pull request?
In the PR, I propose to provide a tip to user how to resolve the issue of
timeout expiration for broadcast joins. In particular, they can increase the
timeout via **spark.sql.broadcastTimeout** or disable the broadcast at all by
setting **spark.sql.autoBroadcastJoinThreshold** to `-1`.
You can merge this pull request into a Git repository by running:
$ git pull https://github.com/MaxGekk/spark-1 broadcast-timeout-error
Alternatively you can review and apply these changes as the patch at:

Improving the error message for broadcast timeouts
I added a recommendation for increasing broadcast timeout. This sentence is
added to existing error message:
```
You can increase the timeout for broadcasts via
${SQLConf.BROADCAST_TIMEOUT.key}
```
