[Cloud] [IPP] Thoughts on static resource uploads

Hi,

I agree with Mike's suggested SM Service / IPP Printer resource
storage elements/attributes and the auto-mapping of the HTTP
PUT (by the MFP to the Resource object attributes (also, certainly
we should add the Static type of MessageCatalog).

Smith - the thing about the access control is the MFD *itself*
(or it's IPP Proxy) is the only one that can store resources in
the Infrastructure/Cloud Printer.  The ordinary end user at the
IPP Client can only read the data (e.g., icon) according to the
type (e.g., you can't read a font, just it's metadata) but can that
ordinary end use can *never* modify or delete any of the resource
metadata or data.

And see Mike's note about the HTTP access for the MFD while
I was writing this.

Cheers,
- Ira
