Fix Issue #333

Summary: The variables are one thing that should be extensible but
due to use of || the specified variables in the agent recipe
always overrode any new varaibles added via attributes. This fixes
the problem by merging all defined attributes in order of
inheritence.

Set default empty hash for logstash_config LWRP

hash for `variables`. But what if you don't want any variables?! We can
just assume a default empty hash.
