[SPARK-25893][SQL] Show a directional error message for unsupported Hive Metastore versions

Browse source 
## What changes were proposed in this pull request?

When `spark.sql.hive.metastore.version` is misconfigured, we had better give a directional error message.

**BEFORE**
```scala
scala> sql("show databases").show
scala.MatchError: 2.4 (of class java.lang.String)
```

**AFTER**
```scala
scala> sql("show databases").show
java.lang.UnsupportedOperationException: Unsupported Hive Metastore version (2.4).
Please set spark.sql.hive.metastore.version with a valid version.
```

## How was this patch tested?

Manual.

Closes #22902 from dongjoon-hyun/SPARK-25893.
