Nils Dijk d03e9ca861 Feature: cstore table options (#25) 
DESCRIPTION: Add UDF's to maintain cstore table options

This PR adds two UDF's and a view to interact and maintain the cstore table options.

 - ``alter_cstore_table_set(relid REGCLASS, [ options ... ])``
 - ``alter_cstore_table_reset(relid REGCLASS, [ options ... ])``
 - ``cstore.cstore_options``

The `set` function takes options and their specific types. When specified it will change the option associated with the table to the provided value. When omitted no action is taken.

The `reset` function takes options as booleans. When set to `true` the value of the option associated with the table will be reset to the current default as specified by the associated GUC's.

The options view containes a record for every cstore table with its associated settings as columns.
