Infrastructure UI plugin API: Add 'resource' method

Add new method 'infrastructure.resource' for retrieving resource
objects from the infrastructure section. Specify the type as a
string (i.e, 'pod' 'cluster' or 'host') and the entire resource object
will be returned, including listView, actions, createForm,
etc. Updating the data in this resource will automatically update the
UI.
