[SPARK-3298][SQL] Add flag control overwrite registerAsTable /
registerTempTable
https://issues.apache.org/jira/browse/SPARK-3298
add a flag `allowOverwrite` to control registerTempTable.
By default it is `true` means register table will overwrite the previous
table.
(like var tempTable)
If set it to `false`, means the registerTempTable command will check the
table name exists or not and if exists, throw a table already exists
exception. Then you should drop it first and then register it again.
(like final tempTable)
