### What changes were proposed in this pull request?
1.`FOLLOW_HIVE_TABLE_LOCATION_ENABLED` in
`org.apache.spark.sql.internal.StaticSQLConf`
2. `FOLLOW_HIVE_TABLE_LOCATION_ENABLED` judge condition branch in
`org.apache.spark.sql.hive.HiveExternalCatalog#getLocationFromStorageProps`
### Why are the changes needed?
**Step 1**,When hive support is enabled and we use sparksql create and save
hive table as fellow：
`df = spark.createDataFrame([{"a": "x", "b": "y", "c": "3"}])`
`df.write.format("orc").option("compression",
"ZLIB").mode("overwrite").saveAsTable('test_spark');`
**Step 2**,When we alter table name through hive interface not spark like
below：
`alter table test_spark rename to test_spark2;`
The location of `test_spark` is changed to `test_spark2` but spark maintain
the path serde `test_spark`，this lead to spark read `test_spark` while
`test_spark2` is expected.
**Step 3**, In order to compatible with historical behavior：
we can use `FOLLOW_HIVE_TABLE_LOCATION_ENABLED` to decide if we need to
follow hive table location.
### Does this PR introduce _any_ user-facing change?
Yes，if we need to follow hive table
location，`spark.sql.follow.hive.table.location` could be set to `true` in
`conf/spark-defaults.conf`
### How was this patch tested?
Manual test.
