Jay Pipes 624f18417b placement: adds ResourceClass.create() 
Adds in the implementation of objects.ResourceClass.create() with checks
that the custom resource class being added doesn't overlap with any
standard (or previously-added custom) resource classes. The
implementation uses a hard-coded number 10000 to mark the start of
custom resource class integer identifiers to make it easy to
differentiate custom resource classes. Note that we do NOT increment the
object version here because nothing as-yet calls the ResourceClass
object.

Also note that this patch adds a required "CUSTOM_" namespace prefix to
all custom resource classes. Followup patches will also place this
constraint into the JSONSchema for POST /resource_classes. The CUSTOM_
namespace is required in order to ensure that custom resource class
names never conflict with future standard resource class additions.
