For the two currently supported engine-specific options, the collmod command will handle parsing the arguments and tell the CollectionCatalogEntry to update it's flags option. This removes the ability of storage engines to have custom options that can be changed after the collection is created. There were issues related to argument validation and replication of changes (including for initial sync). A correct solution will be designed as SERVER-17320.
