Right now when new file-system support has to be added to views, we need to add code to include several more key value pairs into the conf to make it work.
Usually these key value pairs are file-system class names, secret key and access key.
following 2 changes are proposed.
1. load the complete core-site and hdfs-site into the conf for creating filesystem. This will load any secret key, access key configured. It will also load any other necessary parameters.
2. Create a new view setting's parameter per view which will have semi colon separated key=value pairs that needs to be loaded into conf for connecting to the filesystem. This will cover any extra parameters.
