centralize listCollections calls:
- doc validation uses dataService.listCollections but should be collection-model.get() to get collection details
- lots of listCollections code in instance-model. move to collection-model.list()
- dataService has a lot of code that should be in models
- add
type,options.viewOn,options.pipelineandinfo.readOnlyto collection-model - make a
mongodb-view-modelclass that extendsmongodb-collection-model?
