Move iteration of cart items addition to server-side

[ivansg44]

Split several views into multiple functions

• Splits

  • context split into get_context_response and get_context

  • delete_context split into delete_context_response and delete_context

  • create_context split into create_context_response and create_context

  • specifications split into get_specifications_response and get_specifications

  • delete_specifications split into delete_specifications_response and delete_specifications

  • create_specifications split into create_specifications_response and create_specifications

• The "response" methods are accessible through an API url, while the "non-response" methods are purely server-side

  • The purely server-side "non-response" methods allow you to modify the @context and specifications of packages without having to make calls from the front-end

  • Useful for strictly server-side operations

  • The "response" methods functions call the "non-response" methods, have the same API urls as the previous "non-split" methods, and therefore provide the same functionality as the "non-split" methods before

New chain of events when adding cart items

• geem_cart.init_cart_tab calls new method geem_api.GeemAPI.get_cart_items

• geem_api.GeemAPI.get_cart_items calls new method views.ResourceViewSet.add_cart_items_to_package

• views.ResourceViewSet.add_cart_items_to_package calls several methods for each cart item to add it to the target package

• An object detailing the result of each attempted cart item addition makes its way back to geem_cart.init_cart_tab, which reports any failures

• @ddooley I removed code that was responsible for the old way of doing things in commit 1dadcde

  • Please review this commit, and tell me if you are okay with getting rid of this code, or if you want to keep this code around for the future--in which case I can revert the commit

Small changes

• Added a damion_packages.json fixture, which provides a useful set of packages to work with during the development stage

• Removed 127.0.0.1 mapping of db port

  • Makes debugging of database difficult when using docker-machine
