Modified node to node_name in cs_location function as 'node' is a reserved attribute

When attempting to implement the cs_location function in this module I ran into a syntax error whenever attempting to define a "node" underneath cs_location.

Here is the received error:

err: Could not retrieve catalog from remote server: Error 400 on SERVER: Syntax error at 'node'; expected '}' at /srv/puppet/stage/modules/prism/manifests/redisserver.pp:113 on node redis-test01

My resolution for the error was to modify 2 files and change all instances of "node" to "node_name" because the variable "node" is already reserved.
