Add Jar command should support space in file path and in file name.

during add jar operation if file path contain space in folder name or file name contain space.

then java.lang.illegalargumentexception will come from SessionState.validateFiles

Please check this : AddResourceProcessor.run , here command getting splited based on space, i feel this login is not correct. 

Example: add jar "/User/ankitrajboudh/test dir/ankitraj test.jar"  - this command i have run from ./spark-sql , which will use internally hive code.
