    [SPARK-24068][BACKPORT-2.3] Propagating DataFrameReader's options to Text datasource on schema inferring

    ## What changes were proposed in this pull request?
    
    While reading CSV or JSON files, DataFrameReader's options are converted to Hadoop's parameters, for example there:
    https://github.com/apache/spark/blob/branch-2.3/sql/core/src/main/scala/org/apache/spark/sql/execution/DataSourceScanExec.scala#L302
    
    but the options are not propagated to Text datasource on schema inferring, for instance:
    https://github.com/apache/spark/blob/branch-2.3/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/csv/CSVDataSource.scala#L184-L188
    
    The PR proposes propagation of user's options to Text datasource on scheme inferring in similar way as user's options are converted to Hadoop parameters if schema is specified.
    
    ## How was this patch tested?
    The changes were tested manually by using https://github.com/twitter/hadoop-lzo:
    
    ```
    hadoop-lzo> mvn clean package
    hadoop-lzo> ln -s ./target/hadoop-lzo-0.4.21-SNAPSHOT.jar ./hadoop-lzo.jar
    ```
    Create 2 test files in JSON and CSV format and compress them:
    ```shell
    $ cat test.csv
    col1|col2
    a|1
    $ lzop test.csv
    $ cat test.json
    {"col1":"a","col2":1}
    $ lzop test.json
    ```
    Run `spark-shell` with hadoop-lzo:
    ```
    bin/spark-shell --jars ~/hadoop-lzo/hadoop-lzo.jar
    ```
    reading compressed CSV and JSON without schema:
    ```scala
    spark.read.option("io.compression.codecs", "com.hadoop.compression.lzo.LzopCodec").option("inferSchema",true).option("header",true).option("sep","|").csv("test.csv.lzo").show()
    +----+----+
    |col1|col2|
    +----+----+
    |   a|   1|
    +----+----+
    ```
    ```scala
    spark.read.option("io.compression.codecs", "com.hadoop.compression.lzo.LzopCodec").option("multiLine", true).json("test.json.lzo").printSchema
    root
     |-- col1: string (nullable = true)
     |-- col2: long (nullable = true)
    ```

    @MaxGekk, BTW, it's not automatically closed when backporting PR is merged into other branches. Mind manually closing this please?
