## What changes were proposed in this pull request?
Since current `HiveShim`'s `convertFilters` does not escape the string literals. There exists the following correctness issues. This PR aims to return the correct result and also shows the more clear exception message.
**BEFORE**
```scala
scala> Seq((1, "p1", "q1"), (2, "p1\" and q=\"q1", "q2")).toDF("a", "p", "q").write.partitionBy("p", "q").saveAsTable("t1")
scala> spark.table("t1").filter($"p" === "p1\" and q=\"q1").select($"a").show
+---+
| a|
+---+
+---+
scala> spark.table("t1").filter($"p" === "'\"").select($"a").show
java.lang.RuntimeException: Caught Hive MetaException attempting to get partition metadata by filter from ...
```
**AFTER**
```scala
scala> spark.table("t1").filter($"p" === "p1\" and q=\"q1").select($"a").show
+---+
| a|
+---+
| 2|
+---+
scala> spark.table("t1").filter($"p" === "'\"").select($"a").show
java.lang.UnsupportedOperationException: Partition filter cannot have both `"` and `'` characters
```
