WIP: Use local ref-engine discovery for layouts
Bump the layout to v1.1 to support this. This makes it possible to distribute layouts that use other protocols, for example new ref-engine protocols or a sharded blob store [1]. You can also reference external ref- and CAS-engines, although obviously the utility of such depends on the availability of those external engines. [1]: opencontainers#449 Signed-off-by: W.
