[SPARK-15763][SQL] Support DELETE FILE command natively
## What changes were proposed in this pull request?
Hive supports these cli commands to manage the resource [Hive
Doc](https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Cli) :
`ADD/DELETE (FILE(s)<filepath..>|JAR(s) <jarpath..>)`
`LIST (FILE(S) [filepath ...] | JAR(S) [jarpath ...]) `
but SPARK only supports two commands
`ADD (FILE <filepath> | JAR <jarpath>)`
`LIST (FILE(S) [filepath ...] | JAR(S) [jarpath ...])` for now.
This PR is to add the DELETE FILE command into Spark SQL and I will submit
another PR for the DELETE JAR(s).
`DELETE FILE <filepath>`
## **Example:**
**DELETE FILE**
```
scala> spark.sql("add file /Users/qianyangyu/myfile.txt")
res0: org.apache.spark.sql.DataFrame = []
scala> spark.sql("add file /Users/qianyangyu/myfile2.txt")
res1: org.apache.spark.sql.DataFrame = []
scala> spark.sql("list file")
res2: org.apache.spark.sql.DataFrame = [Results: string]
scala> spark.sql("list file").show(false)
+----------------------------------+
|Results |
+----------------------------------+
|file:/Users/qianyangyu/myfile2.txt|
|file:/Users/qianyangyu/myfile.txt |
+----------------------------------+
scala> spark.sql("delete file /Users/qianyangyu/myfile.txt")
res4: org.apache.spark.sql.DataFrame = []
scala> spark.sql("list file").show(false)
+----------------------------------+
|Results |
+----------------------------------+
|file:/Users/qianyangyu/myfile2.txt|
+----------------------------------+
scala> spark.sql("delete file /Users/qianyangyu/myfile2.txt")
res6: org.apache.spark.sql.DataFrame = []
scala> spark.sql("list file").show(false)
