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