Allow Hive to read hive scripts from any of the supported file systems in hadoop eco-system

Current hive cli assumes that the source file (hive script) is always on the local file system. This patch implements support for reading source files from other file systems in hadoop eco-system (hdfs, s3 etc) as well keeping the default behavior intact to be reading from default filesystem (local) in case scheme is not provided in the url for the source file.
