oplog upload/download (#214)

- Feature: Zen server endpoint `prj/{project}/oplog/{log}/chunks` to post multiple attachments in one request.
- Feature: Zen server endpoint `prj/{project}/oplog/{log}/save` to save an oplog container. Accepts `CbObject` containing a compressed oplog and attachment references organized in blocks. 
- Feature: Zen server endpoint `prj/{project}/oplog/{log}/load` to request an oplog container. Responds with an `CbObject` containing a compressed oplog and attachment references organized in blocks.
- Feature: Zen server endpoint `{project}/oplog/{log}/rpc` to initiate an import to or export from an external location and other operations. Use either JSon or CbPackage as payload.
  - CbObject/JSon RPC format for `import` and `export` methods:
  - CbObject RPC format for `getchunks` method, returns CbPackage with the found chunks, if all chunks are found the number of attachments matches number of chunks requested.
- Feature: Zen server `{project}/oplog/{log}/{hash}` now accepts `HttpVerb::kPost` as well as `HttpVerb::kGet`.
- Feature: Zen command line tool `oplog-export` to export an oplog to an external target using the zenserver oplog export endpoint.
- Feature: Zen command line tool `oplog-import` to import an oplog from an external source using the zenserver oplog import endpoint.
