refs #5614, #5943 - adds a new 'filter' bookshelf plugin which extends the model - the filter plugin provides handling for merging/combining various filters (enforced, defaults and custom/user-provided) - the filter plugin also handles the calls to gql - post processing is also moved to the plugin, to be further refactored/removed in future - adds tests showing how filter could be abused prior to this commit
