[SPARK-19912][SQL] String literals should be escaped for Hive metastore
partition pruning
## What changes were proposed in this pull request?
Currently, HiveShim's `convertFilters` does not escape the string literals.
This PR fixes the following cases.
**BEFORE**
```
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|
+---+
+---+
```
**AFTER**
```
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|
+---+
| 2|
+---+
```
