Add policy interface for InlineVariablesRule

[GoogleCodeExporter]

Description of the desired feature(s) (incl. use cases, if applicable)
The current InlineVariablesRule works for a specific case. Inlining of 
functions and variables that the top level of the query plan. I suggest 
changing the structure to include an interface that would allow other policies 
to be created for wider usage of this rule. For example inline only reference 
variable for the whole plan. Here is a patch to add the interface and include 
the default policy of the current state.

This issue takes the place of my concerns on #95 and #96.
