Create resource configuration modal

[keanelekenns]

Essentially we want the existing resource configuration tile to become a modal that is centered and overlayed on top of the screen.

The main difference is that the resource type will not be configurable in this modal. This is covered by #192.

This brings some logic changes that will also likely need to be integrated with @brennanwilkes' new resource class (please update this description with more details if I am leaving something important out)

The new modal should contain just what is circled here (settings determined based on what specific resource type is selected in #192). Also, the delete button should only be present if the resource is being modified, but not if it is being created (this logic already exists)

Pretty sure this is implemented already, although I am not sure who did it
