ZEO proxies the standard storage API.

The original requirement is for ZEO to support storages which expose extended 
functionality via an extended API. DirectoryStorage uses this to allow 
control of its snapshot mode.

It would be mildly disappointing if there was no way of accessing an extended 
storage API over ZEO. However I have no concerns about seeing 
getExtensionMethods replaced with some alternative mechanism (possibly more 
complex for the consumer(s) of this extended API, if that makes it more 
sustainable within ZEO)
