    [SPARK-17967][SPARK-17878][SQL][PYTHON] Support for array as an option for datasources and for multiple values in nullValue in CSV

    ## What changes were proposed in this pull request?
    
    Multiple values in `nullValue` is actually more reasonable and `read.csv()` in R already supports it. In practice, there might be many values that should be treated as `null`. Also, this matches the behaviour to R's one as well.
    
    This PR suggests to add an API in Python, Scala and Java that takes `Array[String]` and the support for multiple values in `nullValue` option in CSV.
    
    In case of R, there seems requiring to be more changes. This will be followed up by this PR.
    
    ## How was this patch tested?
    
    Unit test in `readwriter.py`, `CSVTypeCastSuite.scala` and `CSVSuite.scala`.

    Rather than just submitting code, can you put down the interfaces concisely either in a doc or the pr description? As @falaki said, we need this to work in DDL too. It is possible to just extend the DDL syntax to support multiple values.

    Thanks @gatorsmile. Sure, let me open a smaller one and cc you.
    
    I know one reference in R:
    
    ```R
    > d <- "col1,col2
    + 1,3
    + 2,4"
    > df <- read.csv(text=d, na.strings=c("3", "2"))
    > df
    ```
    ```
      col1 col2
    1    1   NA
    2   NA    4

    I have hesitated to submit this PR due to this problem for few weeks. After thinking hard, I decided to submit this.
    
    The test below:
    
    ```scala
    ...
     .option("some-null-value-option", null) 
    ```
    
    was testing of setting `null`. Because `String` is the only reference type (we have `Double`, `Long` and `Boolean` which are `AnyVal` and they can't be null), 
    it was fine so far.
    
    Now, `Array[String]` is added and the compiler gose confused and therefore we should explictly give the type to `null`.
    Unless we do a runtime checking, it seems we can't add overrien versions anymore without fixing this test.
    
    So, yes, it will break the APIs if any users were setting `null` without type but I wonder if it is worth to keep this behaviour. There are a lot of APIs that do not allow `null` without type so far, e.g., `functions.array(null)`.

    For SQL, rather than "array", can we follow Python, e.g.
    
    ```
    CREATE TEMPORARY TABLE tableA USING csv
    OPTIONS (nullValue ['NA', 'null'], ...)
    ```

    @HyukjinKwon as I laid out in the JIRA a major problem with this approach for specifying multiple options is that it won't work in DDL. What is wrong with having a numbered list. E.g.: `nullValue1, nullValue2, etc`
