currently when trimming we overload the trim method, but should probably create a new separate interface for gc/trim-full. this should also change the behavior to trim at the real object's...

when creating objects add metadata like its stripe and object position to allow validation.

but always default to the safest option (all omap) if we can't figure out something that works.

this is useful in the multi-writer case or when the cli is allowed to update options that should be propagated to clients via the view mechanism.

head objects are properly prefixed, but for easier filtering we need to be able to find link objects as well.

use a simple object listing plus filtering, but record some where the potential to create a set of registry nodes.
